When Do Great Pyrenees Stop Growing?

A frequently asked question is when the Pyrenees stop growing. After all, they are enormous dogs. By the time your dog reaches his first birthday, he should have attained around his full height.

He is expected to continue gaining weight and filling up until he is 18 – 24 months old, but the majority of his growth should occur prior to his first birthday.

Great Pyrenees Growth Chart – What To Expect
Great Pyrenees Weight Chart by Age

Great Pyrenees Weight  1-2 weeks

A Great Pyrenees puppy will typically weigh around a pound at birth. They do develop swiftly, and should reach a weight of 2 pounds within a week.

In two weeks, they should have gained at least three pounds. Large breed dogs typically acquire weight rapidly, and you should not be surprised to see some major rapid growth immediately. At this age, they will still be nursing on mother’s milk.

Great Pyrenees Weight 3-12 weeks

By the age of three weeks, your puppy should weigh approximately four pounds. By the time your dog reaches the age of 12 weeks, he should weigh between 30 and 40 pounds.

They should gain about 2.5 pounds each week on average, although this can vary depending on the dog and whether it is a male or female Great Pyrenees. While the rapid growth may surprise you, keep in mind that these are enormous dogs.

Great Pyrenees Weight 4-6 months

At six months of age, a male Great Pyrenees weighs between 70 and 80 pounds. A six-month-old female Great Pyrenees, on the other hand, will weigh between 50 and 60 pounds. Males and girls will both require significant additional growth before reaching adult size.

Great Pyrenees Weight  7-12 months

When your dog is seven months old, he should be significantly larger. A 7-month-old puppy’s weight should be between 59 and 81 pounds. Although the dog is not yet completely matured, he is obviously growing in size.

By the time he is a year old, his weight will have stabilized. At one year, the range is 75 to 109 pounds. Even yet, this is a highly improbable final weight for your dog.

Great Pyrenees Adult Weight 

Your dog’s final adult weight should be approximately 18 months. The Great Pyrenees can reach a final weight of between 82 and 124 pounds, however these are only averages.

He may be larger or smaller than average, depending on his genetic predisposition for weight gain or loss. You do not want to allow your dog to expand beyond his development curve, since excess weight might be detrimental to his joints.

What is the Full Grown Great Pyrenees Weight?

The Great Pyrenees are considered to be a huge breed. The breed standard specifies a typical and average size range of 25-32 inches in height and 85-160 pounds in weight.

The height difference between a fully developed female and male Great Pyrenees is minimal. Males, like many breeds, are slightly taller than females, although only by an average of 2 to 3 inches.

When fully grown, female Great Pyrenees measure between 25 and 29 inches, while males measure between 27 and 32 inches.

How To Weigh Your Great Pyrenees Puppy?

If you want to maintain track of your Great Pyrenees’s weight, you must first learn how to weigh him properly.

To begin, you should be able to weigh your Great Pyrenees at home if he is a puppy or if you are just large enough to hold him. This can be accomplished with a standard bathroom scale.

To begin, weigh yourself and record the result. Then, while standing on the scale, pick up your dog and hold him. The difference in weights represents your dog’s weight.

If your dog is too huge to carry, you can either invest in a dog scale, which can cost upwards of $100, or contact your veterinarian. The majority of veterinarian offices will enable you to use their scale.

Unless there is a health problem, you can weigh an adult Great Pyrenees once every six months. Once a week is sufficient for a puppy to ensure he is growing normally.

What Is A Great Pyrenees’s Neck Size?

To determine the neck size of your dog, use a soft and flexible tape measure to determine the neck size of your dog where her collar naturally falls. Then, put two fingers between your dog’s neck and the tape measure to ensure that the dog collar fits snugly but comfortably. Great Pyrenees’s average neck circumference is between 23 and 27 inches.

How big do they get?

According to the American Kennel Club’s (AKC) Official Breed Standards1, a male Great Pyrenees should weigh at least 100 pounds and stand between 27 and 32 inches tall from the ground to the top of the shoulders. Female Great Pyrenees are smaller in stature than males, weighing in at over 85 pounds and standing between 25 and 29 inches tall.

A mature Pyrenean Mountain Dog, according to the AKC, should have a muscular body beneath its thick coat, with a short, strong neck, a somewhat deep chest, and a long tail that hangs low to the ground. This breed is distinguished by its graceful movement and magnificent appearance.


Great Pyrenees Body Condition Score (BCS) 

Veterinarians utilize the Body Condition Score to determine a dog’s fat content in order to develop an exercise and food program that is appropriate for your puppy’s activity level, body type, and lifestyle. BCS has two scales: 1-5 and 1-9.

A Great Pyrenees with a healthy weight should have a BCS of 3/5 or 5/9. This is when you can feel your puppy’s ribs with your fingers through a thin coating of fat.

This also means that a belly tuck may be seen from the side and a waistline can be seen from above.

Factors That Affect Great Pyrenees Puppy Growth 

Genetics

Genetics will play a role in determining the size of your dog. While he will always be a large dog, his size will vary.

While there is no perfect size for a Great Pyrenees, there are certain averages that might assist you in determining the proper size for your dog. Genetics will make this determination for you. Whatever food you feed your dog, you will never be able to overcome his DNA.

Diet & Nutrition

Nutrition will undoubtedly have an impact on your puppy’s growth. You’ll want to feed your dog high-quality puppy food to ensure that he grows as quickly as he should.

Overfeeding your dog will not grow him taller, but it will put undue strain on his joints and increase his risk of hip dysplasia. It is critical to monitor your dog’s growth.

Physical Activity & Health

You’ll want to ensure that your puppy receives adequate exercise while he’s a puppy to ensure he grows to be as muscular as you like.

You also do not want to over-exercise your puppy, so pay attention to his indications about when he needs to rest. Never overburden him, but ensure he gets enough outside playing to stay healthy.

How Much Does It Cost To Own A Great Pyrenees?

When considering adopting or purchasing a Great Pyrenees, it’s important to prepare ahead financially so that the pet does not become a financial burden on you or your family later on. You should include in not only the cost of the dog, but also the cost of training, food, supplies, veterinarian fees, grooming, and other additional charges. To assist you in budgeting for your new dog’s arrival, we’ve created a cost calculator that will provide an accurate idea of the cost of raising a Great Pyrenees.

All of this adds out to a total cost of ownership of between $71,145 and $194,620.

How To Help Your Great Pyrenees Lose Weight If He Is Overweight 

As with humans, exercise is critical for your overweight dog’s health. Increased movement helps your dog burn off excess energy (and calories consumed). Avoid panic! Exercising your pet does not have to include marathons or lengthy hikes. Regular walks and the opportunity to run and play safely off-leash. 

Even creating a stimulating indoor environment that encourages your dog to exercise on a regular basis can help. Bear in mind that different breeds require varying amounts of exercise, so visit your veterinarian, breeder, or your dog’s breed standard for recommendations on recommended activity levels.

Distinguish Begging from Hunger

Distinguish Begging from Hunger
Distinguish Begging from Hunger

Begging is not necessarily motivated by a desire for more food; it is also used to gain attention. (And, by rewarding the behavior, you reinforce and encourage it to continue.) If your dog begs, do not automatically assume he is hungry. Trust your instincts and keep track of the date and time of your last meal. 

If your dog is prone to begging and you are prone to succumb to those puppy dog eyes, choose a high-protein meal with a fiber blend to help control your dog’s hunger and voluntary food consumption. In this manner, you may feed your dog with the assurance that he will feel fuller and content for a longer period of time.

Restriction on treats and table scraps

Even when our dogs are not begging, many of us provide an excessive amount of treats and table scraps. Dogs are not required to share our food! Consider treats and scraps for your pet in the same way that you would candy for children to help you keep them in check. If you’re going to utilize snacks for training, choose low-calorie, low-fat ones and keep the portions small. 

As an alternative, keep in mind that clickers are excellent for reinforcement and they have no calories! After all, a few extra pounds can make a significant impact in the lives of dogs, which are significantly smaller than humans. (Even the colossal breeds!) Therefore, focus on a balanced diet and resist the temptation to “reward” them with extra.

Customize Your Dog’s Diet

Not all weight-loss foods are created equal, which is why it’s critical to match your dog’s nutrition plan to their unique needs. Choose a brand that caters to your dog’s unique needs, whether they be weight control, dietary sensitivities, or illnesses.
