Great Pyrenees Growth Chart & Weight Calculator

Do you have a Great Pyrenees pup and wonder how tall he or she will grow? Our growth calculator and charts will predict your dog’s adult weight. Simply put in your pup’s weight and age into our calculator and we will estimate the adult size!

Great Pyrenees Weight Calculator & Growth Chart

All dog breeds have some size variation in adult dogs. This calculator can help give you an idea of the expected adult size of your pup.
Note that the weight before 6-8 weeks of age does not say a lot about the adult size of a dog. Especially high or low birth weights can be due to intrauterine placement (essentially where the pup was in the mom’s tummy and how much nutrition he got). Pups with the lowest birthweight can grow up to be the largest of the litter, and the largest can end up as the smallest!

How big will my Great Pyrenees get?

The American Kennel Club calls for Great Pyrenees to grow up to reach the following weight and height:

  • Females: 25-29 inches at the withers and 85 – 115 lbs
  • Males: 27-32 inches and 100 – 160 lbs

Your Great Pyrenees’ expected adult weight can be predicted with our puppy weight calculator. Of course, it is only an estimation and might vary from your dog’s actual adult size.

 

How long does it take for a Great Pyrenees to be full grown?

You can expect your Great Pyrenees to reach his adult size somewhere around 18-24 months. Most Great Pyrenees come very close to their full-grown height by their first birthday but continue to gain weight, build muscles and fill out afterwards for several more months.

Especially in dogs that have not yet been spayed or neutered the chest and shoulders become broader and more muscular.

Your Great Pyrenees’ coat will also continue to become thicker and gain volume. This might appear as if your dog himself is growing – but some of it is probably “just fluff”.

How much should a 1 year old Great Pyrenees weight?

A male Great Pyrenees should weight at least 95-110 pounds at 1 year of age. A female Great Pyrenees would be slightly smaller at least 80-95 pounds. You can expect your dog to gain another 5-15 pounds between his first and second birthday.

If your Great Pyrenees is considerably smaller and lighter, take him to the vet. An intestinal parasite might cause malnutrition and keep him from growing. As a large breed, Great Pyrenees are prone to being “skinny teenagers” and will require a lot of daily calories during their rapid growth in the first year.

A worm infestation could cause your Great Pyrenees to not grow as usual, however this is quickly diagnosed and treated by a veterinarian.
