Fleas on Dogs 101
Fleas are more than just a nuisance for our canine companions—they’re persistent parasites that can cause discomfort and health issues (including tapeworms, yuck!) if left unchecked. As responsible pet owners, understanding the signs of flea infestations, knowing how to treat them effectively, and implementing preventive measures are necessary. Fleas on dogs are gross, and if you’ve landed on this post, you probably have questions about these tiny little bugs!

In this comprehensive guide, we’ll explore the symptoms of fleas on dogs, discuss treatment options, and outline preventive strategies to help keep your furry friend flea-free and healthy. Whether you’re dealing with a current infestation or looking to safeguard your pet from future flea encounters, this resource aims to provide you with the knowledge and tools necessary for effective flea management!

What are the Symptoms of Fleas on Dogs?

The symptoms of fleas on dogs can vary, but common signs to look out for include:
1. Excessive Scratching and Biting: If your dog is constantly scratching, biting, or licking certain areas of their body, especially around the base of the tail, neck, or groin area, it may indicate flea bites.
2. Redness and Irritation of the Skin: Flea bites can cause redness, inflammation, and small raised bumps on the skin. In severe cases, flea allergy dermatitis (FAD) can develop, leading to intense itching, hair loss, and skin infections.
3. Presence of Flea Dirt (Feces) on the Fur: Flea dirt, which looks like small black specks or pepper flakes, is flea feces. You may notice it on your dog’s fur, particularly in areas where fleas are most active.
4. Restlessness and Irritability: Infested dogs may exhibit behavioral changes such as restlessness, irritability, and difficulty sleeping due to discomfort caused by flea bites.
5. Loss of Appetite: Some dogs may experience a decrease in appetite or reluctance to eat due to the discomfort associated with flea infestations.
6. Excessive Grooming: Dogs may groom themselves excessively in an attempt to relieve itching caused by flea bites. This can lead to hair loss, irritated skin, and the formation of hot spots.
Many people mistake these symptoms for food allergies and switch their pet’s food looking for a solution. However, in many cases, the dog is suffering from fleas or mite bites and irritation!

If you notice any of these symptoms in your dog, especially during warmer months, or if they have been in contact with other animals or infested environments, see a veterinarian.

Read on for our tips to reduce flea infestations, soothe irritated skin, and prevent them from coming back.

What Do Fleas on Dogs Look Like?

Fleas on dogs are small, wingless insects with flattened bodies that are well-adapted for moving through fur. They are typically reddish-brown in color and measure about 1-3 millimeters in length. When viewed up close, fleas appear narrow from side to side and elongated from top to bottom, giving them a flattened appearance.

While adult fleas are relatively easy to see, they are adept at moving quickly through the dog’s fur, making them sometimes challenging to spot, especially in dogs with thick or dark coats. However, you may be able to detect fleas by parting your dog’s fur and examining areas where fleas commonly hide, such as around the neck, ears, groin, and base of the tail.

Additionally, you may notice flea dirt, which looks like small black specks or pepper flakes, on your dog’s fur. This “dirt” is flea feces and is a telltale sign of flea infestation.

It’s essential to regularly check your dog for fleas, especially if they seem uncomfortable, suffer from allergy-like symptoms, spend time outdoors, or interact with other animals. Early detection and prompt treatment can help prevent flea infestations from becoming more severe and causing discomfort for your pet.

The Best Veterinary Flea Treatment for Dogs

Whether you like it or not, most flea infestations require something stronger than home remedies. There is a lot of misinformation about the safety of flea and tick medications, however, these concerns are largely unfounded.

All medications, including home remedies for fleas, can come with side effects. However, failing to treat fleas on a dog can result in health problems that are much, much worse.

Determining the best veterinary flea treatment for dogs depends on various factors, including the dog’s age, weight, health status, lifestyle, and the severity of the flea infestation. Here are some highly effective veterinary flea treatments commonly recommended by veterinarians:
1. Prescription Flea Medications: Veterinarians often prescribe oral flea medications that contain active ingredients such as lufenuron, spinosad, afoxolaner, fluralaner, or sarolaner. These medications are available in chewable tablets or flavored soft chews and work systemically to kill fleas on contact or prevent flea reproduction. Examples include Comfortis, NexGard, Bravecto, and Simparica.
2. Topical Spot-on Treatments: Topical spot-on treatments are applied directly to the skin, typically between the dog’s shoulder blades, and provide long-lasting protection against fleas and ticks. They contain ingredients like imidacloprid, fipronil, selamectin, or permethrin. Examples include Frontline Plus, Advantage II, Revolution, and Vectra 3D.
3. Flea Collars: Veterinary-recommended flea collars contain active ingredients like imidacloprid, flumethrin, or deltamethrin and provide continuous protection against fleas and ticks for several months. Seresto is a popular veterinary-recommended flea collar known for its effectiveness and longevity.
4. Prescription Flea Shampoos and Sprays: In cases of severe flea infestations or allergies, veterinarians may prescribe medicated flea shampoos or sprays containing ingredients like pyrethrins, permethrin, or selamectin. These products provide immediate relief by killing fleas on contact and soothing irritated skin.
When selecting a veterinary flea treatment for your dog, it’s essential to consult with your veterinarian to determine the most appropriate option based on your dog’s specific needs and circumstances. Additionally, follow the manufacturer’s instructions and dosage recommendations carefully to ensure the safety and effectiveness of the flea treatment.

Regular veterinary check-ups and flea prevention measures are essential for maintaining your dog’s health and well-being.
Natural Flea & Tick Treatment For Dogs

Natural flea and tick treatments can be effective for some dogs, but their efficacy may vary depending on factors such as the severity of the infestation, the dog’s sensitivity, and the specific products used.

While a home remedy for fleas may not offer the same immediate and potent results as veterinary products such as Capstar and Advantage II, many pet owners believe them to be safer and more environmentally friendly.

Note that essential oils (commonly used in “natural” flea and tick treatments) are chemicals that can be toxic to dogs. There is a lot more to consider than Earthy marketing!

Here are a few natural flea and tick treatments that can be helpful. Major infections require veterinary treatment (there is no getting around this).
1. Apple Cider Vinegar (ACV) Spray: Mix equal parts of water and apple cider vinegar in a spray bottle and apply it to your dog’s fur, avoiding sensitive areas like eyes and nose. The acidity of ACV repels fleas and ticks and soothes irritated skin.
2. Diatomaceous Earth (DE): Food-grade diatomaceous earth is a fine powder made from fossilized algae. DE works by dehydrating and killing fleas and ticks upon contact. Read our blog post on the safety and efficacy of DE against fleas, as there are special considerations.
3. Wondercide Flea & Tick Spray: this commercially available natural solution contains pet-safe essential oils to deter bugs. If you use anything with essential oils, stick to a well-known product like this one.
4. Regular Grooming and Cleaning: Regularly groom your dog with a flea comb to remove fleas and ticks manually. Wash your dog’s bedding and vacuum your home frequently to eliminate flea eggs and larvae from the environment.
While natural flea and tick treatments can be effective, it’s essential to consult with your veterinarian before starting any new regimen, especially if your dog has existing health conditions or if you’re unsure about the safety of certain ingredients. Additionally, monitor your dog for any signs of sensitivity or adverse reactions to natural products and discontinue use if necessary.
1. Repellent vs. Killer: Natural treatments often work as repellents rather than outright killers of fleas and ticks. They may help deter pests from latching onto your dog but may not eliminate existing infestations as quickly as chemical treatments.
2. Frequency of Application: Natural treatments may require more frequent application compared to veterinary products to maintain their effectiveness.
3. Environmental Management: Combining natural treatments with environmental control measures, such as regular grooming, washing bedding, and vacuuming, can enhance their effectiveness by targeting fleas and ticks at various stages of their life cycle.
4. Individual Variation: Some dogs may respond well to natural treatments, while others may not experience significant relief. Factors such as the dog’s breed, age, health status, and environmental exposure play a role in determining treatment effectiveness.
5. Consistency and Persistence: Consistent and persistent use of natural treatments is key to achieving optimal results. It may take time to see improvements, and regular maintenance is necessary to prevent re-infestation.
Does Dawn Dish Soap Kill Fleas on Dogs?

Dawn dish soap may temporarily kill fleas on dogs, it is not considered safe for use on pets due to its harsh ingredients and potential for skin irritation. Despite its effectiveness in killing fleas, using Dawn dish soap on dogs can strip their skin of natural oils, leading to dryness, irritation, and potential long-term skin issues.

Instead of relying on Dawn dish soap, it’s recommended to use veterinary-approved flea treatments and shampoos specifically formulated for dogs. These products are designed to effectively kill fleas while being gentle on your dog’s skin and coat.

If you’re dealing with a flea infestation on your dog, consult with your veterinarian for safe and effective flea treatment options tailored to your pet’s individual needs. They can recommend the most appropriate flea control products and provide guidance on how to use them safely and effectively.

Is Garlic Effective Flea Control For Dogs?

While some pet owners believe that garlic can be effective for flea control in dogs, there is limited scientific evidence to support its efficacy, and its safety remains a subject of debate among veterinarians.

Garlic contains compounds called thiosulfates, which, when ingested in large quantities, can be toxic to dogs. Ingesting garlic in high doses can lead to a condition called hemolytic anemia, where red blood cells are destroyed, potentially resulting in weakness, lethargy, pale gums, and even death in severe cases.

While the amount of garlic typically used in homemade flea remedies is unlikely to cause immediate harm, long-term or repeated exposure to garlic can pose health risks to dogs. Additionally, the effectiveness of garlic as a flea repellent or treatment is questionable, as fleas may not be significantly deterred by the consumption of garlic.

Instead of relying on garlic for flea control, it’s recommended to use veterinary-approved flea preventatives specifically formulated for dogs. These products are safe, and effective, and provide comprehensive protection against fleas, ticks, and other parasites. Additionally, practicing good hygiene, maintaining a clean living environment, and minimizing exposure to infested animals and environments are essential components of a comprehensive flea control strategy.

If you have concerns about fleas or are considering alternative flea control methods for your dog, it’s important to consult with your veterinarian. They can provide guidance on safe and effective flea control options tailored to your pet’s individual needs and circumstances.

Diseases Caused by Fleas on Dogs

Fleas on dogs can transmit various diseases and health issues, posing risks to both pets and humans. Some of the diseases caused by fleas on dogs include:
1. Flea Allergy Dermatitis (FAD): FAD is a common allergic skin reaction in dogs caused by flea bites. Dogs with FAD may experience intense itching, hair loss, redness, and skin irritation. Continuous scratching can lead to secondary bacterial infections and exacerbate the condition. Many pet owners mistakenly misdiagnose this condition as “food allergies”.
2. Anemia: Severe flea infestations can cause anemia in dogs, especially in young puppies or small breeds. Fleas feed on blood, and heavy flea infestations can lead to significant blood loss over time, resulting in weakness, lethargy, pale gums, and even collapse in severe cases.
3. Tapeworm Infection: Fleas serve as intermediate hosts for tapeworms, parasitic worms that can infect dogs when they ingest fleas during grooming. Symptoms of tapeworm infection in dogs may include scooting, weight loss, vomiting, and the presence of rice-like segments (tapeworm segments) in the feces or around the anus.
4. Hemoplasmosis: Fleas can transmit hemotropic mycoplasmas, bacterial organisms that infect red blood cells, leading to hemoplasmosis in dogs. Symptoms may include anemia, weakness, lethargy, fever, and jaundice.
5. Bacterial Infections: Flea bites can introduce bacteria into a dog’s skin, leading to bacterial infections such as impetigo or cellulitis. These infections may cause skin redness, swelling, pain, and the formation of pus-filled lesions.
6. Vector-Borne Diseases: Fleas can transmit various vector-borne diseases to dogs, including:
- Bartonellosis: Bartonella bacteria transmitted by fleas can cause bartonellosis in dogs, leading to fever, lethargy, swollen lymph nodes, and potentially more severe symptoms.
- Murine Typhus: Fleas infected with Rickettsia typhi bacteria can transmit murine typhus to dogs, resulting in fever, lethargy, joint pain, and gastrointestinal symptoms.
- Cat Scratch Disease: Fleas can transmit Bartonella henselae bacteria to dogs, causing cat scratch disease, which may present with fever, swollen lymph nodes, and flu-like symptoms.
Where Do Dogs Get Fleas From?

Dogs can get fleas from various sources, including:
1. Other Animals: Dogs can pick up fleas from direct contact with other infested animals, such as stray dogs, cats, rodents, or wildlife. Fleas can easily transfer from one animal to another during social interactions, playing, or grooming.
2. Environment: Flea eggs, larvae, pupae, and adult fleas can be present in outdoor environments, including yards, parks, and wooded areas. Dogs can inadvertently pick up fleas while exploring or spending time outdoors, especially in areas frequented by wildlife or other infested animals.
3. Indoor Spaces: Fleas can hitch a ride into indoor environments on clothing, shoes, or belongings and establish infestations in homes. Once indoors, fleas can thrive in carpets, upholstery, bedding, and cracks and crevices, providing ample opportunities to infest dogs and other pets.
4. Flea Infested Items: Dogs can acquire fleas from infested items such as bedding, blankets, carpets, and furniture. Flea eggs, larvae, and pupae may hide in these items and emerge as adult fleas, leading to infestations in dogs and their living spaces.
5. Grooming Facilities or Boarding Kennels: Dogs may come into contact with fleas while visiting grooming facilities, boarding kennels, or pet daycare centers where infested animals are present. Poor hygiene practices or inadequate flea control measures in these environments can contribute to the spread of fleas among dogs.
6. Travel: Traveling to areas with higher flea populations or staying in accommodations where infested animals have been present can increase the risk of dogs encountering fleas.
To prevent flea infestations, it’s essential to regularly inspect dogs for fleas and ticks, use veterinary-approved flea preventatives year-round, practice good hygiene, maintain a clean living environment, and minimize exposure to infested animals and environments. Additionally, consulting with a veterinarian for personalized flea control recommendations can help protect dogs from the discomfort and health risks associated with flea infestations.

Why Is My Dog Throwing Up After Eating?
Experiencing your beloved canine companion throwing up after eating can be distressing and concerning for any pet owner. Concerns about toxins, mold, and disease come to mind. Some may panic about heavy metals in their pet’s food.

While an occasional episode of vomiting may not always be a cause for alarm, frequent occurrences can indicate underlying health issues that require attention.

Similar to humans, dogs can experience digestive issues that lead to vomiting after meals. In this blog post, we will examine the potential causes behind this unsettling behavior and offer guidance on the necessary steps to take next.

Why Is My Dog Throwing Up After Eating?

There are several reasons why a dog might vomit after eating, ranging from mild to serious issues. If your vet is appearing lethargic, disoriented, or weak, see a veterinarian immediately!

Here are some potential reasons for why a dog might throw up after eating:
1. Dietary indiscretion: Dogs are notorious for eating things they shouldn’t, such as table scraps, garbage, or spoiled food. This can lead to upset stomach and vomiting. Even if you believe your pet hasn’t ingested anything they shouldn’t have, it’s essential to recognize that this is a very real and common occurrence.
2. Food intolerance or allergy: Some dogs may have sensitivities or allergies to certain ingredients in their food, leading to vomiting as a reaction. This occurrence would be rare and requires a veterinary diet elimination trial to rule out.
3. Overeating: Eating too much food too quickly can overwhelm a dog’s digestive system, causing vomiting.
4. Gastrointestinal issues: Dogs can suffer from various gastrointestinal problems like gastritis, inflammatory bowel disease, or gastrointestinal obstructions, all of which can cause vomiting.
5. Pancreatitis: Inflammation of the pancreas can lead to vomiting, especially after eating fatty foods.
6. Infections: Viral or bacterial infections, such as parvovirus or gastroenteritis, can cause vomiting as a symptom.
7. Toxic ingestion: Ingestion of toxic substances like plants, household chemicals, or certain human foods (e.g., chocolate, xylitol) can result in vomiting.
8. Motion sickness: Some dogs may vomit in response to car rides or other forms of motion.
Dog Ate Something They Shouldn’t and is Vomiting

If your dog has consumed something they shouldn’t have and is now vomiting, act swiftly!

Do your best to identify what your dog ingested and any potential signs of toxicity. Then immediately contact your veterinarian or an emergency animal clinic to seek guidance.

If your pet ingested something they shouldn’t have but appears stable, you can contact the Pet Poison Poison hotline for advice. This is a paid service, but if you have pet insurance, it may be covered.

Provide them with detailed information about the ingested substance, the time it occurred, and any accompanying symptoms your dog is displaying.

While monitoring your dog closely, refrain from attempting to induce vomiting unless specifically instructed by a veterinary professional, as some substances can exacerbate the situation if brought back up.

Pay close attention to any changes in your dog’s condition, such as increased lethargy or distress, and follow any advice provided by your vet, which may include seeking immediate veterinary care or administering first aid at home.

Do not give your dog hydrogen peroxide without veterinary guidance.
Toxic Ingestion in Dogs

Toxic ingestion in dogs occurs when they consume substances that are harmful to their health.

The following things are toxic to pets and may require immediate attention:
- Grapes
- Chocolate
- Onions
- Certain plants (indoors and out)
- Many wild mushrooms
- Many essential oils
- Rat poison
- Household chemicals and cleaning agents
- Automobile fluids such as gas and oil
- Coolant (for your car, which is often sweet to the taste and thus appealing)
- Xylitol (found in candy and gum)
- Medications (including pet medications on which they may overdose)
- Weed and other recreational drugs
In many cases, if your dog is throwing up because they ate something toxic, it’s an emergency. Go to the veterinarian immediately.

Symptoms of toxic ingestion vary depending on the substance ingested but may include vomiting, diarrhea, lethargy, tremors, seizures, difficulty breathing, and collapse.

Unless a veterinarian or the pet poison hotline tells you to, refrain from using hydrogen peroxide to induce vomiting in your dog. This outdated practice is associated with many complications and may alter the way a veterinarian can treat your pet.
Dog Illnesses that Cause Digestive Problems

Several illnesses and conditions can cause dogs and puppies to vomit. All of these require immediate veterinary care (I’m sensing a theme here!).
1. Gastroenteritis: Inflammation of the stomach and intestines, often caused by infections (bacterial, viral, or parasitic) or dietary factors.
2. Inflammatory Bowel Disease (IBD): Chronic inflammation of the gastrointestinal tract, leading to symptoms like vomiting, diarrhea, and weight loss.
3. Foreign Body Ingestion: Swallowing objects like toys, bones, or pieces of clothing can cause blockages in the digestive tract, leading to vomiting among other symptoms.
4. Parasitic Infections: Infestations with parasites such as roundworms, hookworms, or giardia can cause gastrointestinal symptoms including vomiting.
5. Liver or Kidney Disease: These conditions can lead to vomiting as well as other symptoms like jaundice, increased thirst, and changes in urination.
6. Gastric Dilatation-Volvulus (GDV), or bloat: A serious condition where the stomach fills with gas and twists, often seen in large, deep-chested breeds. This is a medical emergency requiring immediate veterinary attention. Dogs with bloat will often attempt to vomit but may be unable to produce anything.
7. Parvo: this serious and deadly condition is preventable with vaccination. It is most often seen in puppies (who aren’t fully vaccinated), however, all dogs are at risk.
My Dog Eats Too Fast and Throws Up

It’s common for dogs to eat too quickly, leading to vomiting. Contrary to popular belief, a dog shouldn’t wolf down their meal and lick the bowl clean.

Rapid eating can cause your dog to swallow air along with their food, leading to gastrointestinal discomfort and sometimes regurgitation.

Here are some steps you can take to help your dog slow down while eating and reduce the chances of vomiting:
1. Slow-Feeding Bowls: Use specially designed slow-feeding bowls or puzzle feeders that have obstacles or compartments, making it more difficult for your dog to gulp down food quickly. I like the Kong Wobbler and this viral bone bowl.
2. Small, Frequent Meals: Instead of feeding your dog one or two large meals per day, consider splitting their daily food portion into smaller, more frequent meals. This can help prevent your dog from feeling overly hungry and devouring their food too quickly.
3. Hand Feeding: If your dog’s eating habits are severe, consider hand-feeding them small amounts of food at a time. This allows you to control the pace at which your dog eats and can help prevent vomiting. You can keep the food in a treat pouch and use it for training rewards, too!
4. Food Moistening: Adding water or low-sodium broth to your dog’s kibble can help slow down eating and also provide additional hydration. Stuff the rehydrated food in a West Paw Toppl and use this as enrichment.
5. Medical Evaluation: If your dog continues to vomit frequently despite your efforts to slow down their eating, it’s important to consult with your veterinarian. Persistent vomiting could indicate an underlying medical condition that requires attention.
Pancreatitis Symptoms in Dogs & Puking

Pancreatitis in dogs presents with various symptoms, with vomiting being one of the hallmark signs.

Alongside vomiting, dogs with pancreatitis may exhibit abdominal discomfort, decreased appetite, lethargy, and in some cases, fever and diarrhea.

The vomiting may occur repeatedly and can sometimes contain bile or blood. Pancreatitis requires medical treatment, including fluid therapy, pain management, and dietary adjustments.

Untreated pancreatitis can lead to severe complications. Go to the vet!

Your veterinarian can perform diagnostic tests to confirm the diagnosis and create a tailored treatment plan to address your dog’s specific needs.

Treatment of pancreatitis commonly involves administering intravenous fluids to address dehydration and restore electrolyte balance. Pain management medications may be prescribed to alleviate discomfort, while antiemetics can help control vomiting.

Depending on the severity of the condition, nutritional support may involve withholding food temporarily to allow the pancreas to rest before gradually reintroducing a bland, easily digestible diet such as Hill’s Science Diet Low Fat i/d Digestive Care (only available through your veterinarian).

Is Purina Making Dogs Throw Up and Have Seizures?

In 2023, a post on social media went viral, suggesting that Purina dog food contained toxic levels of heavy metal and was causing dogs to throw up, have seizures, and die.

The original post was debunked and has since been removed. Despite this, a group of fringe “holistic” veterinarians and one of the plaintiffs in the Hill’s Science Diet Vitamin D recall lawsuit used the social panic over Purina Food to build engagement with their content.

They led and fostered the creation of a fringe extremist community whose beliefs ride on the idea that all kibble is toxic and that veterinarians are intentionally harming pets with food, vaccines, and medications.

This has led to a flood of misinformation circulating on social media platforms concerning veterinarians, Purina, and other kibble brands. If you’ve heard chatter about Purina food being toxic, or veterinarians harming pets for profit, it’s likely coming from this group.

Tread cautiously with social misinformation and double-check the sources of where you hear things.

If your pet is throwing up after eating kibble, and you are concerned that the food itself is the cause, keep the food (in the original bag) and see a veterinarian.

Blood and stool samples can help your veterinarian determine if your pet has ingested something toxic. If the food might be a possible suspect based on the evidence at hand, your veterinarian can facilitate the next steps.

Salmonella and Bacteria Making Dogs Sick

Salmonella and certain types of bacteria can indeed cause dogs to vomit. Despite a common myth suggesting dogs are immune due to their stomach acidity, they’re still susceptible. Contrary to popular belief, dogs’ stomachs are less acidic than those of humans.

While a dog is less likely to show severe symptoms than a human, the bacteria load can make them feel icky and can be damaging to their internal gut health.
1. Salmonella: Dogs can become infected with Salmonella bacteria through consuming contaminated food, such as raw meat or eggs, kibble that has been recalled, or through contact with feces (including their own) from infected animals. Salmonella infection, known as salmonellosis, can lead to symptoms including vomiting, diarrhea (often bloody), fever, lethargy, and loss of appetite. It can be particularly dangerous for young puppies, elderly dogs, or those with weakened immune systems.
2. Other Bacterial Infections: Various other bacteria, such as Escherichia coli (E. coli), Campylobacter, or Clostridium perfringens, can also cause gastrointestinal infections in dogs. These bacteria are commonly found in contaminated water, soil, or raw food. Symptoms may include vomiting, diarrhea, abdominal pain, fever, and dehydration.
Dogs with bacterial infections can shed the bacteria in their stool and saliva, putting humans at risk, too.

Preventing bacterial infections in dogs involves practicing good hygiene and food safety measures. Here are some tips:
- Proper Food Handling: Ensure that your dog’s food is handled and stored safely, especially raw meat and eggs, to prevent contamination with harmful bacteria like Salmonella.
- Cooking: Cook meat thoroughly before feeding it to your dog to kill any potential bacteria. Avoid feeding raw meat diets unless properly prepared and handled to minimize the risk of bacterial contamination. Note that raw meat diets are associated with a much higher risk of medication-resistant bacteria such as E. coli.
- Hand Washing: Wash your hands thoroughly with soap and water after handling raw meat or coming into contact with feces, and encourage family members to do the same.
- Clean Environment: Keep your dog’s living environment clean, including their food and water bowls, bedding, pooping, and living areas, to reduce the risk of bacterial contamination.
- Regular Veterinary Care: Ensure your dog receives regular check-ups and vaccinations to help maintain their overall health and immune function, which can reduce the risk of bacterial infections.
If you suspect your dog has ingested something contaminated with bacteria or if they show symptoms of vomiting or diarrhea, consult your veterinarian for proper diagnosis and treatment. In severe cases, bacterial infections may require antibiotics or other medications to resolve.

The Best Flea and Tick Medicine for Great Danes
It’s May, and that means that the fleas, ticks, mites, and other creepy crawlies are lurking. Dogs living in most areas of the United States benefit from year-round flea and tick protection. Today we’re talking about the best flea and tick medicine for Great Danes.

In addition, I will cover the following topics:
- Is flea and tick medicine safe for dogs?
- Are there natural alternatives to flea and tick medicine?
- Does flea and tick medication cause seizures?
- How much does flea and tick medication cost?
- Are pills, topicals, or collars more effective at preventing parasites?
- What happens if I don’t protect my dog from fleas and ticks?
This is a huge topic and hopefully a great resource for you! Let’s dig in.

The Best Flea and Tick Medication for Great Danes

There are many flea and tick preventatives to choose from, and everybody will have a different opinion on this (especially because there is a lot of scary stories and misinformation out there!)

Different medications may be more or less effective, depending on where you live, too!

In some areas, fleas and ticks have become resistant to certain medications (especially in bug-infested areas where many pet owners decline flea and tick prevention for their pet). Local veterinarians know what the statistics are and what brands are working to prevent parasites.

We’re going to share some of the most commonly used flea and tick preventatives for Great Danes, including information about Bravecto, Sentinal, Nexguard, and natural solutions.

What Happens if I Don’t Use Flea & Tick Prevention?

Outside of the obvious answer here (keeping fleas and ticks away from your dog), many people are unaware that the proper use of veterinary parasite prevention can also prevent and treat:
- Hookworms
- Roundworms
- Heartworms (spread by mosquitoes)
- Tapeworms
- Whipworms
- Mites (a common cause of chronic ‘allergies’ and itching!)
Not all medicines or natural solutions treat all of those things; it is important to discuss this with your vet and make sure that your pet is fully covered against everything, including fleas and ticks.

Mites bite and cause itching and skin and ear irritation. They are a common and often overlooked source of allergy symptoms in Great Danes.

Of course, the above parasitic infections are pretty gross, but fleas and ticks kind of take the cake here.

Fleas cause itching and “allergy” symptoms. Left untreated, they can also cause welts and intense itching that leads to scabs and skin infections. Many people think their dog is allergic to something in their food, when really, their dog has fleas! Fleas are highly contagious and once they enter your home (via your dog), they are hard to eradicate. Not only that, they will bite humans too! Yuck!

Ticks are a common parasite that carry disease. They are often found in grass, wood, and shade and will attach themselves to the host (your dog), often undetected. They bury their head into the skin, suck the blood out, spread disease, and then use the blood to reproduce.

A tick bite can result in loss of coordination, bacterial infection, Lyme disease, or even death among a laundry list of nasty side effects ticks bring with them to your pet.

Is Flea & Tick Medication Safe for Dogs?

Yes. Of course, there are some different schools of thought on this. In looking at evidence-based veterinary medicine and research, flea and tick medications are safe for your pet.

To be perfectly honest, you do not want to mess around with Ehrlichiosis, a flea-infested couch, or worse…heart worms either, right?

The treatment for existing parasitic infections, especially heart worms, can be pretty nasty.

A very small percentage of dogs have had a notable reaction to flea and tick medications. In many of those cases those dogs had underlying health conditions, had unknowingly been given dangerous and toxic fake knockoff products, or may actually have been poisoned by something else (and the application timing of flea/tick products was purely coincidental).

These cases are well documented not only by the veterinary community but by the manufacturer of the flea/tick medication as well. Seresto Collars and Bravecto chews are commonly faked and sold as authentic!

Many peer-reviewed studies have been done on the safety and efficacy of modern flea & tick preventatives. In some studies, pets were given extremely large doses over long periods of time with no ill effects.

Read this SNOPES article on Bravecto Chews

Does Flea & Tick Medication Cause Seizures?

Many companies and influencers who wish to sell ‘natural’ preventatives will say that flea and tick medications cause seizures and death.

Studies also show that false or misleading content online spreads faster than truthful content.

A quick google search turns up many popular influencer blogs which lay claims to veterinary preventatives being “nothing more than poison for your pet”. These claims are not actually supported by the regulations, research and science behind flea and tick medications.

Side effects are a risk with any medication or treatment you give your dog (and this includes common procedures such as teeth cleaning or vaccination against rabies).

The small risk of side effects, especially when looking at dogs with no known pre-existing seizure activity or health condition is greatly eclipsed by the sheer volume of dogs who suffer (or even die) needlessly from preventable parasitic infections.

The vast majority of dogs experience no side effects at all with veterinary-backed preventatives, and unlike their unprotected counterparts, they are MUCH less likely to suffer from parasitic illnesses, heart worm, itching, and skin infections.

Fake dupes of flea & tick preventatives can be dangerous and are responsible for many cases where serious side effects have been seen.

I’m going to share more information about knockoff Seresto Collars and more below, so you can learn how to avoid fakes and keep your pet safe.

Safest Oral Flea & Tick Medications for Great Danes

We always recommend talking to your vet about flea and tick prevention, as most of these medications require both a blood test and a prescription.

Don’t let that scare you off. The blood test looks for existing heart worm infections. This is important because oral prevention only targets heart worm larvae, NOT adult worms (which will have filled your dogs heart chambers with large worms that look like spaghetti).

A dog with an existing heart worm infection needs treatment first before taking preventatives.

Once your dog is cleared to take preventatives, your veterinarian will write you a prescription for one or more of the following products (depending on your pet, their weight, and what tends to work best for the pets that are seen in their location). We recommend ONLY purchasing directly from your Veterinarian or Chewy.com, never from other sources (where fakes and dupes may be sold).

Bravecto – Flea & Tick

Bravecto is a dog chew that must be given at a specific dose (based on weight) every three months to prevent fleas, ticks, and mites. It must be used in tandem with another medication to prevent worms (including heart worm), so it is commonly prescribed alongside Sentinal. You can view Bravecto Chews HERE.

Sentinal Spectrum – Parasites

Sentinal Spectrum is a monthly dog chew (based on weight) that prevents heart worms, tapeworms, hookworms, roundworms, and whipworms. When used among a large population of pets, medications like this also help control the flea population (by stopping eggs from hatching)! You can view Sentinal Spectrum HERE.

NexGard – Flea & Tick

Like Bravecto, Nexgard provides protection against fleas, ticks, and mites. It uses a different active ingredient than Bravecto, and must be given monthly (vs. every 3 months). It must be paired with another medication that target parasites such as heart worm and round worm. Nexgaurd is often paired with Heartgard. You can view Nexgard HERE.

Heartgard – Parasites

Heartgard is monthly oral preventative that targets heart worm, roundworm and hookworm. It does not work on whipworm or tape worm, so it’s not as comprehensive as Sentinal. Heartgard is often paired with Nexguard. You can view Heartgard HERE.

Simparica Trio – Flea, Tick, & Some Parasites

Simparica Trio is a great solution for Great Dane owners who want comprehensive oral protection against fleas, ticks, and some parasitic worms (including heart worm, hookworm, and round worms) in one dose. This oral medication requires a prescription and must be given monthly. You can view Simparica Trio HERE.

Trifexis – Flea, Heartworm & Some Parasites

Like Simparica, Trifexis is a once-monthly prescription preventative that targets not only fleas and heart worms but several parastic worms as well (hookworm, roundworm and whipworm). Trifexis does not target ticks and will need to be used in tandem with another product. You can view Trifexis HERE.

Do Flea & Tick Collars Work?

Many people prefer topical treatments or flea and tick collars to chewables. There are some pros and cons to this route.

Unlike chewables, topicals and collars don’t typically always require a prescription. However, their effectiveness can be reduced by bathing or for dogs that like to swim a lot. Additionally, collars can get lost and they can be dangerous for dogs to wear unsupervised.

It’s important to note that some dogs and some people are sensitive to the chemicals on topical versions (including collars) and care should be used around children or sensitive individuals.

Unlike oral medications, topical medications and collars can be dangerous for all pets and humans to ingest. Thus, topical flea and tick prevention is not always ideal for homes with cats (who are especially sensitive to certain ingredients).

Many flea and tick collars and topicals do NOT prevent internal parasites such as whip worm, round worm and heart worm; you’ll likely still need a chewable or secondary product for that.

Seresto Collar – Fleas & Ticks

The Seresto collar is a popular option for those looking to keep fleas and ticks at bay. It’s easy to wear and lasts nearly 7 months. Unlike oral preventatives, the Seresto collar does not require a prescription. You can view the Seresto Collar HERE.

Advantage Multi Topical – Parasites & Worms

Advantage Multi requires a prescription and is a topical medication that prevents multiple worms & parasites, including fleas. It does not prevent ticks, so like most topicals, comprehensive protection using multiple products is needed. You can view Advantage Multi HERE.

Frontline Plus Topical – Fleas & Ticks

Frontline Plus is a popular topical that must be applied every month. This formula kills fleas, ticks, and some mites and is easily found at local grocery stores or online without a prescription. You can find Frontline Plus HERE.

Does Natural Flea & Tick Prevention Work?

Unlike veterinary prevention, most “natural” and “holistic” options have not been widely subjected to rigorous and thorough clinical trials and testing for longevity, safety and efficacy.

While some research and limited private testing has been done (usually showing that directly spraying live bugs with the essential oils in the product tends to kills them), it doesn’t often address any potential health (or olfactory/scent) concerns related to prolonged exposure of these same ‘natural’ chemicals on dogs and cats.

The EPA barely regulates ‘natural’ pesticide products at all, so there is no guarantee that what is in the package will be safe or effective.

That doesn’t mean that natural solutions aren’t helpful, but it’s important to understand that even ‘natural’ prevention utilizes chemicals. Commonly used essential oils such as peppermint, citrus, rosemary, lemongrass and cedarwood are in fact chemicals. They aren’t well regulated though, and there is a wide range of quality and concentrations from brand to brand.

Some of those oils (peppermint for example), are toxic to dogs and cats.

Not only that, but essential oils have a very strong scent; dogs may not show signs of discomfort but make no mistake, their incredibly sensitive noses may very well be annoyed (or even harmed) by it. Remember, there isn’t a lot of clinical research.

Plant Based Flea & Tick Products Safety & Efficacy

Sprays and collars that utilize essential oils are often marketed as being safe because they are ‘plant powered’. This feel good marketing disregards the fact that many “plant powered” things are in fact toxic.

I’ve yet to find any research showing that prolonged exposure to certain essential oils is safe, or that liberal use of essential-oil based flea and tick products on the yard is safe for wildlife and vegetation.

In “natural” oral (chewable) preventatives, garlic is commonly used. In small amounts that is ok, but in amounts large enough to actually be effective against fleas and ticks, the dose would likely be toxic to your pet. We don’t recommend oral ‘natural’ oral flea & tick prevention chews for any reason.

Natural prevention has its merits, but in many cases, it’s nothing more than snake oil. Most veterinarians (save for a few fringe types who are often trying to sell a product) will tell you that they see more dogs in their office for parasites who had been on ‘natural’ preventatives than any other.

Evidence shows us that that ‘natural’ products are simply not as effective, as much as we want it to be. The false assumption of protection complicates things even further, as pet owners are led to believe that ‘holistic’ options are just as effective (they aren’t).

According to this study, ‘natural’ solutions may actually be harmful, citing that “Ninety-two percent of animals (n = 44) showed presence of one or more adverse effects.“

More research is definitely needed, and I encourage caution around the kind of ‘holistic’ pet care marketing which implies that ‘natural’ is always good and veterinarian-recommended & science-backed products are always bad.

Essential Oil Based Anti-Parasite Solutions

If you are still interested in ‘natural’ solutions, there are some options. The Wondercide brand has done *some* studies which is also helpful, although their research is not nearly as comprehensive as it needs to be to compete against proven veterinary products. They do not test their products for safety and long term use on animals, so your pet is the test subject.

However, among the many options Wondercide is one of the more thoughtfully formulated natural insect repellent products. If you would like to check them out to use as part of a more comprehensive parasite protection plan, we’ve provided some links below!

I like to spray the edge of our deck with Flea & Tick yard spray to reduce bugs on summer evenings, and I occasionally lightly treat my cloths and my pets fur if we are going into dense or wooded areas.

Wondercide Flea & Tick Yard Spray

This solution of essential oils can be sprayed around your yard to reduce the chance of fleas and ticks on or around your property. It does need to be applied liberally and often (especially after rain or sprinkler use), but may be helpful if you live in an area plagued with pests. You can view Wondercide Flea & Tick yard spray here.

Wondercide Pet & Home Spray

Heading out of your house and want to give your dog a little extra boost in protection? Wondercide pet spray may help ward of pests, especially when used in tandem with veterinary preventatives. You can use this to spray down your dogs coat (make sure to reapply often, especially if your dog goes for a swim). As with any preventative, talk to your veterinarian and monitor your dog for negative reactions (including eye irritation, itching, hives, or drooling). You can view Wondercide Pet & Home Spray here.

Wondercide Flea & Tick Collar

The Wondercide Flea and Tick collar targets fleas, ticks, and mosquitoes with essential oils. Reviews on the efficacy in real life applications of this are mixed, and it’s important to keep in mind that the collar will be in close proximity to your dogs nose (potentially bothering their olfactory sense with ongoing exposure). You can view Wondercide Flea & Tick Collar here.

Itching, Allergies, Mites & More

I touched on this above, but many chronically itchy dogs are misdiagnosed with food allergies.

This is a huge problem. Desperate pet owners are switching food brands again and again, often landing on poorly formulated foods that are loaded with lentils and potatoes instead of meat, just to get rid of the itching.

Many times, those chronically itchy dogs are actually suffering from mites or fleas.

Fleas and mites often go undetected; if your dog is not protected, they are at risk. Dogs that are on research-backed parasite prevention are less likely to suffer from chronic itching and other bug-based ailments.

It is very important to talk to a veterinarian and even a veterinary dermatologist if your dog is suffering from itching, scratching, ear infections, scabs, and ongoing skin problems.

How Much Does Flea & Tick Prevention for a Great Dane Cost?

This is where Great Dane owners tend to experience the biggest sticker shock.

Big dogs = big expenses, and because most oral flea and tick medications are dosed based on weight, expect to pay significantly more than you would if your dog was a chihuahua.

I recently renewed our prescription for Bravecto & Sentinal. For two Danes and a small dog it was several hundred dollars out of pocket, but it’s worth it for the peace of mind.

Ultimately, prevention is a whole lot cheaper, and definitely a lot safer, than having to treat my dogs for preventable diseases (especially heart worm and Lyme’s Disease, yikes!).

If cost is an issue, talk to your veterinarian about the most effective and economical option. For those times when oral prevention is out of reach financially, a flea + tick collar is your best bet!

Counterfeit Flea & Tick Products

Fake counterfeit flea & tick meds are a huge problem, and dangerous too. Many documented severe reactions to flea and tick products were the result of a product that only looked like the real thing.

Seresto Collars are one of the most commonly duped products.

To protect yourself and your pet from fake flea and tick medications, the EPA has shared some helpful tips.

As mentioned previously, we only recommend getting your flea/tick meds through your veterinarian or a quality online veterinary pharmacy that your veterinarian approves of.

Never purchase Seresto collars or other flea/tick preventatives from private sellers or unknown websites.

We recommend steering clear of Amazon for the same reason.

As always, talk to your veterinarian. They have a PhD and several years of clinical practice under their belt; we promise, they (like us here at Hello Danes) want your pet happy and healthy!
