Great Dane puppies grow incredibly fast. We recommend referencing our Great Dane puppy growth chart to learn just HOW fast you can expect your puppy to grow.
PRO TIP – Take lots of photos!!! These babies gain size at an insane rate, especially in the first 6 months of life.
Keep in mind that these numbers are all averages! Your Great Dane puppy may be above or below these numbers depending on genetics, health and the nutrition that is provided.

What are the BEST foods for Great Dane Puppies?
Great Dane puppies are surprisingly lean! This is better for their growth, joints and overall health. Your puppy should have nice fur, bright eyes, tight feet, confidence, and lots of energy when awake.
The explosive growth period in Great Dane puppies happens from 6 weeks until 6 months. They slow down around then and will eat less, but will continue to grow for much, much longer!
When do Great Danes Stop Growing?
On average, Great Dane puppies continue to grow until age 2, at which point they will fill out (develop more muscle mass and breadth of chest and hips).
Knuckling is a serious problem in Great Dane puppies that results from explosive growth, incorrect nutrition, and slick or hard surfaces. Read more about knuckling below!

Bigger Is Not Better
There seems to be this fear that our Great Dane puppies just aren’t growing big enough or fast enough.
There is also a subtle competition at play to have the largest Dane, a contest that often begins with breeders who are breeding for size rather than for structure, health and type.
Adding nutrition, fat, and toppers to your Great Dane Puppies diet to ‘fill them out’ or ‘bulk them up’ is one of the worst things you can do. A Great Dane should be lean, muscular, and athletic.
It’s not a race. Slow growth and building towards an appropriate height and weight is the healthiest choice.
You may be looking for a European Great Dane growth chart. European Great Danes and American Great Danes follow breed standards that are nearly identical, and the chart we’ve included in this post is ideal for all Great Danes.

Some breeders have made it their mission to promote bulkier, heavier, droopier Danes as ‘Euro’, often at the expense of the dogs orthopedic structure, eyes and overall health. ‘Euro’ is an aesthetic preference and not actually a sign that a dog is truly ‘European’ or well bred. For more information on the great ‘Euro’ vs. ‘American’ discussion, read our post below.
Great Dane Puppy Growth
Keep in mind that our Great Dane growth chart represents the ‘average’.
Your puppy may not fall exactly into the range, and that may be ok!
If your puppy has health problems (including HOD or megaesophagus), comes from smaller genetics, was the ‘runt’ of the litter, failed to thrive or had a rough start they may be on the small side.
If your puppy comes from a lineage of bigger-boned dogs with a lot of substance or is provided too much nutrition too fast, they may be on the large side.

How to Weigh a Great Dane
None of this matters if you cannot actually weigh your Great Dane and keep track of their growth scale!
Here are some tips:
- Weigh yourself first. Then reset the scale, hold your puppy and weigh again. Subtract your weight from the weight of you + the puppy combined.
- Visit the veterinarian. Make going to the vet, stepping on the scale, seeing the vet techs and leaving super fun.
- Visit your local pet store. Petsmart and some Petco stores that have an in-house veterinarian will often let you use their scale for free! Always ask first. (NOTE: we do not recommend taking young puppies into Petsmart: get those vaccines first!).
- Ask your groomer or breeder if they have a scale you can borrow.
Use lots of treats and make the process of being weighed positive! Some puppies are afraid of the slick shiny surface. You can always teach your puppy to sit on a towel, and then put the towel onto the scale to transfer the behavior.
What Age is a Great Dane Puppy Fully Grown?
Great Dane puppies experience explosive growth for the first 8 months, after which they tend to slow down. Your puppy will likely eat less and may appear to have stopped growing.
At this point, however, they are far from done!
Great Danes will grow in height until they are nearly 2 years old. It is at this age that the growth plates will close and it is appropriate to spay or neuter.
After age 2, they will continue to fill out. Do not mistake this process for getting fat! Many Great Danes are spayed or neutered at this age and become overweight because of the sudden drop in hormones.
Filling out means:
Deeper and fuller chest
Wider and more developed hips
Maturation of the head structure
Muscle development at the shoulders, hips and thighs
Coverage that reduces the lanky puppy look
Did you know that waiting to spay or neuter until your puppy is more mature may help reduce the risk of hip dysplasia, ACL/CCL tears, some cancers and poor adult structure?
