Whether you have just adopted or are planning on adopting a Great Pyrenees dog, you will want to use a Great Pyrenees growth chart to help you keep track of your dog’s growth and development.
The charts are used to help you work out how large your dog should be once he is done growing. Following a growth chart is an excellent way to ensure your dog is as healthy as he should be.
We have broken down everything that you need to know about a growing Great Pyrenees to help you out. This is what you will want to know.
When Do Great Pyrenees Stop Growing
A common question is when do Great Pyrenees stop growing. After all, they are large dogs, so you might be wondering. By the time that your dog has reached his first birthday, he should be about his full height.
He is likely to continue to gain weight and to fill out all the way up to 18 – 24 months, but the bulk of his growth should happen before his first birthday.
It is best to follow a growth chart in order to be sure that your dog is growing at the rate that is healthy. If you have any concerns, talk to your vet.
Great Pyrenees Weight Chart
We have built a growth chart for your Great Pyrenees to help guide your through your pup’s development. It is important to note that male and female dogs are not the same size.
Female dogs are generally smaller than male dogs, so you cannot use the same Great Pyrenees growth chart for them.
For example, if your female pup is 30 pounds at the age of 3 months, you can expect her to weigh about 63 when she is 7 months.
Likewise, a male puppy who is 37 pounds at 3 months will likely weigh 77 pounds at the age of 7 months. Using these estimates can help you work out whether your dog is growing at the right weight for his individual size.
Using the Great Pyrenees weight chart, you will be able to line up the dog’s age by month with how much they should weigh.
Great Pyrenees Puppy Weight Chart
|Age||Weight in lbs||Weight in kg|
|3 Months||37 lbs - 40 lbs||16.5 kg - 18 kg|
|4 Months||48 lbs - 50 lbs||21.5 kg - 22.5 kg|
|5 months||59 lbs - 63 lbs||26 kg - 28 kg|
|6 months||69 lbs - 73 lbs||31 kg - 33 kg|
|7 months||77 lbs - 81 lbs||35 kg - 36.5 kg|
|8 months||83 lbs - 88 lbs||37.5 kg - 40 kg|
|9 months||88 lbs - 92 lbs||40 kg - 41.5 kg|
|10 months||94 lbs - 99 lbs||42.5 kg - 45 kg|
|11 months||99 lbs - 103 lbs||45 kg - 46.5 kg|
|12 months||102 lbs - 109 lbs||46 kg - 49 kg|
|14 Months||105 lbs - 115 lbs||47.5 kg - 52 kg|
|16 Months||110 lbs - 124 lbs||50 kg - 56 kg|
Generally, your dog should stay and the same growth rate until he has finished growing, so make sure that is not gaining weight unnecessarily.
Great Pyrenees Growth Chart – What To Expect
Birth – 2 Weeks
At birth, on average, a Great Pyrenees puppy will weigh around a pound at birth. They do grow quickly, and within the week, they should be up to 2 pounds.
At 2 weeks, they should be already up to 3 pounds. Typically, large breed dogs will gain weight quickly and you should not be surprised to see some seriously rapid growth right away. They will still be on mother’s milk at this age.
3 Weeks – 12 Weeks
By 3 weeks of age, your puppy should weigh around 4 pounds. By the time that he is 12 weeks of age, you can expect your dog to weigh between 30 and 40 pounds.
Really, they should be gaining around 2.5 pounds a week, but that will vary depending on the dog and whether you have a male or female Great Pyrenees. The rapid growth might be surprising, but remember that these are large dogs.
4 Months – 6 Months
When your puppy has reached 4 months of age, he should weigh between 37 and 50 pounds, depending on whether your dog is a male or female and whether he is predisposed to being a smaller or larger dog. By 6 months, he should be between 53 and 73 pounds.
You should notice that the range is getting broader between averages as your pup grows, but as long as he’s on his curve, that is ok.
7 Months – 12 Months
Your dog should be a lot bigger when he is 7 months old. The range for a 7 month old puppy is between 59 and 81 pounds. The dog is not quite fully grown, but he is definitely getting bigger.
By a year of age, his weight will be slowing down. The range at a year is 75 to 109 pounds. Even then, this is unlikely to be your dog’s final weight.
The final adult weight of your dog should be set around 18 months. Great Pyrenees can be between 82 and 124 pounds as a final weight, but those are just averages.
He might be larger or smaller depending on what he is naturally prone to being weight-wise. You do not want to allow your dog to get any bigger than his growth curve, because too much weight can be unhealthy for his joints.
Factors That Affect Great Pyrenees Puppy Growth
Genetics will help determine how big your dog will be. While he will inevitably be a large dog, how large he is will vary.
There is no correct size with a Great Pyrenees, but there are averages that will be able to help you determine the right size for your dog. Genetics will determine this for you. No matter what kind of food your feed your dog, you will still not be able to beat out his genetics.
Nutrition will definitely affect your puppy’s growth. You will want to ensure that you are feeding your dog quality puppy food to make sure that he will grow as well as he should be growing.
Feeding your dog too much will not make him taller, but it will put too much pressure on his joints and put him at a bigger risk of hip dysplasia. It is important to make sure that your dog is growing at an appropriate rate.
Physical Activity & Health
You will want to make sure that your dog is getting enough exercise while he is a puppy to ensure that he will grow to be as muscular as you want him to be.
You do not want to over-exercise your puppy either, so take your puppy’s cues when he needs to rest. Never push him too hard, but make sure he is getting enough outside play time to be healthy.
How Long Are Great Pyrenees Pregnant?
If you have a pregnant Great Pyrenees, you might be wondering what you are dealing with as far as time goes. On average, the normal gestation for a dog is about 63 days from conception, though this can vary by a few days.
Breeders usually have the gestations literally down to a science. If you are not entirely sure when your dog conceived, your veterinarian should be able to give you some guidance and even do an ultrasound to see what you are working with. The gestation time can be a few days off, even if you know the date of conception.
How Many Puppies Do Great Pyrenees Have?
Since Great Pyrenees are incredibly large dogs, you can expect them to have large litters of puppies. On average, you can expect your dog to have litters of 8 to 10 puppies, but there is still a lot of variety.
Even if your dog has previously had puppies, there is no guarantee that your dog will have the same amount each time. Sometimes your dog may have a litter of 10, but then next time will only have 1 pup. Regardless, you can prepare to have several puppies since that is more likely than fewer.
What Is The Life Expectancy Of Great Pyrenees?
Like we said Great Pyrenees are a large breed of dogs, so unfortunately, we will only get 10 to 12 years with them. The larger dogs always leave us too soon, but you can work toward ensuring your pup has a longer life by giving him the healthiest food that he can get plenty of exercise.
By keeping him healthy and active, you will help keep your friend around for a longer period of time. Also make sure to keep up with any routine vet visits to look out for any illnesses that can be prevented.
What If My Great Pyrenees Is Not The Right Weight?
If you are concerned that your dog isn’t the right weight, there are a few things to think about. The first is whether your dog is still on his growth curve if he is still growing. While weight charts are an excellent guide, they are not perfect.
That said, there are some things that you can watch for. Great Pyrenees are fluffy and furry, so it might be harder to identify a waist.
Normally, you are looking for a defined waist with a dog, but with a fluffy dog, you will want to look at his haunches. Can you see a waist raise up in the back? If there is any hanging you might have an overweight dog.
If your dog is overweight, which you should confirm with your vet, you will need to figure out a better activity level and confirm that your dog is eating the right amount of food.
How Much Does It Cost To Own A Great Pyrenees?
The cost of adopting a Great Pyrenees will depend on whether you are getting one from a breeder or a shelter. That cost is not a constant.
You can get an idea of how much it will cost to own one, however. The first year of your dog’s life, you can expect to pay about $3,000, depending on whether you are spaying or neutering your pup.
After the first year, the care of your dog should cost around $2,200 a year, which includes food, medical costs, grooming expenses, and any other odds and ends.
How To Safely Manage Growth Of Your Great Pyrenees?
In order to safely manage the growth of your Great Pyrenees, you will need to make sure that you are following his growth regularly.
Following the great pyrenees weight chart will help you know what to expect with your dog and to help make sure that he is growing at the right pace.
Beyond watching the growth chart, you will need to make sure that you are feeding your dog the right kind of food. You should also make sure that your dog is getting plenty of exercise, whether you are taking him on walks, to the dog park, or even just on playdates with other dogs.
Additionally, having routine checks with your vet will also make sure that your dog is growing well and very healthy. You will also want to make sure that your dog is properly groomed regularly, especially since these dogs have a lot of fur to take care of.
Great Pyrenees Genetics And Common Health Problems
Like all purebred dogs, Great Pyrenees are prone to certain health conditions. Luckily, they are typically pretty minor. Genetic conditions that your dog might inherit include entropion, which is an eye condition, skin conditions, and might even have hip dysplasia.
Sometimes, the dogs might develop other conditions, like osteosarcoma, which is a kind of bone cancer. Regardless, maintaining regular visits with the vet can help you identify any of these conditions and treat them before they become a problem.
If your dog is at risk of any of these conditions, your vet might recommend that you come in more frequently for checkups.
