The Great Pyrenees is a big furry ball of love. They are affectionate, independent, and enjoy being part of a family. These canines are also known as “Pyrenean Mountain Dogs.” As our dogs grow, monitoring their growth, especially during puppyhood, is good to see if they are growing up healthily. This includes their weight and the milestones that come with growing up. Understanding this is one of the best ways to ensure your dog is healthy throughout her life.

Every dog is unique. Some may be bigger than the breed standard, while others may be smaller. Measuring them allows us to see if our dogs are on track. Some grow bigger faster, whereas others take longer to grow up. Keeping note of milestones gives us points of comparison to see how well our dogs develop. A few factors go into our dogs’ growth, regardless of gender or breed.

Our comprehensive guide looks into your Great Pyrenees’ growth throughout their early years. We’ve also provided a growth chart as a handy resource to refer back to during your dog’s life. Finally, we answer the most frequently asked questions about your dog as they develop.

What To Expect

Let’s look at the specifics of what to expect during their growth period. This information will help you prepare for changes as your puppy grows. This is also an excellent time to learn the different developmental changes in your dog’s life during their most crucial developmental stage — puppyhood. It is important to note that although growth charts are helpful, all dogs are different, and their growth stages may differ.

Reminders

This article explores the growth patterns of a typical Great Pyrenees. However, remember that your puppy’s results may vary. They may have growth spurts or plateaus that speed up or slow overall growth. This is normal and is no cause for worry. The Great Pyrenees typically reach their full height by their first birthday, though their weight continues to develop until they are 24 months old.

This growth also depends on nutrition and overall health, so be sure not to overfeed or underfeed your dog. You must also keep them away from injury. Ultimately, your puppy might be slightly smaller or larger than our averages. If you are alarmed by this, it’s always a good idea to contact your veterinarian.

Puppy Growth Timeline

Great Pyrenees Puppy Food
Your Great Pyrenees Puppy will need food that can help sustain his rapid growth requirements.

Here is a timeline of your Great Pyrenees’ growth, plus the different developmental milestones and needs your puppy may require.

Here’s what to expect from your Great Pyrenees for the first year of their life.

Birth To 2 Weeks

Your puppy is not very interactive at this time because they are both blind (due to sealed eyelids) and deaf. They rely on their mother to give them the care and milk they need. If you also care for their mother, ensure she is eating and resting enough to give the puppies good care. Allow your puppy to drink as much milk as they need. Around the two-week mark, your puppy’s eyes start to open, and they begin hearing sounds.

1 Month

At the one-month mark, your dog has developed much of his senses. They will play and socialize with their littermates. This is especially important for their early development, as this is their first chance to socialize. One month old is also when they begin to wean off their mother’s milk. You can start feeding them soft, wet dog food. It’s important not to shock them with too much food at once.

  • Males weigh an average of 5-10 pounds.
  • Females weigh an average of 5-10 pounds.

2 Months

When your puppy reaches two months old, they should be able to be separated from their mother, as they are now fully weaned off milk. You can start giving them three meals daily, with portion sizes changing according to size and weight. You can begin teaching them basic commands and start with obedience training.

Early training for the Great Pyrenees is vital. It’s essential to train them now because they are the most receptive when they are very young. This sets a foundation for a well-behaved dog later down the line. They tend to be independent and somewhat stubborn with following commands. They can also be protective of their family, which will cause them to bark. This breed is a barker. The more they are exposed to people, animals, and noises, the greater the likelihood of your doggy remaining calm. Here is the weight you can expect from your Great Pyrenees at two months old.

  • Males weigh an average of 15- 30 pounds.
  • Females weigh an average of 10- 25 pounds.

3 Months

You should continue your puppy’s training and socialization, but it may be a good idea to start leash training them now to get used to the feel of the harness and leash. Ideally, it would be best if you prepared your Great Pyrenees not to pull on the leash, or else he will be walking you. This is also the right time to get them used to grooming. Consistency and patience are key here. They are very playful and particularly mouthy. Do your best to curb bad behavior and encourage acceptable behavior.

  • Males weigh an average of 30- 40 pounds.
  • Females weigh an average of 25-35 pounds.

4 Months

Your puppy starts being a lot more playful by the time they reach four months old. At this point, they should also be happily settled in with you at home. You should continue their obedience training and socialization using positive reinforcement as much as possible. If you’re less experienced in training a dog like a Great Pyrenees, you may want to enroll in training classes. You can also let your doggy join in on puppy kindergarten classes as a way to teach them to behave appropriately around other dogs. This makes for a confident, friendly, and well-rounded puppy.

  • Males weigh an average of 45-55 pounds.
  • Females weigh an average of 35-45 pounds.

5 Months

At around five months, you may be astonished at just how large your Great Pyrenees has been getting. It may be more difficult to rein them in when they are rambunctious due to their larger size. This is a stage where they learn, grow, and play at a fast rate. We encourage you to continue with the positive reinforcement, as this can make all the difference in how your dog grows. Great Pyrenees grow to be very affectionate and loving, but puppies will be puppies. Patience is key here, so try to enjoy them while they’re still young.

  • Males weigh an average of 60-70 pounds.
  • Females weigh an average of 45-55 pounds.

6 Months

At around the six-month mark, your Great Pyrenees is getting taller and heavier. She may be asking for a lot of exercise, but since she is still growing, it is important not to overexert her, as this can injure them. More seriously, it can result in hip dysplasia. Six months means you have established a routine in your everyday life with your dog. Keep being the firm, consistent, and confident leader they need so that they can learn discipline and structure.

  • Males weigh an average of 70-80 pounds.
  • Females weigh an average of 50-60 pounds.

7 Months

When your dog has reached seven months old, they should be very set in their day-to-day life with you since you have established routine and rapport. Continue being firm in your discipline with them, and always reward exemplary behavior. You can start taking your dog on longer walks but not too long to exert her. You could even split the walks into two smaller sessions. Great Pyrenees are prone to hip dysplasia and bloat, so their exercise needs to be moderated until they are two years old. You can also give your dog two meals per day now, as long as they get enough food for their age, size, and activity level.

  • Males weigh an average of 75-85 pounds.
  • Females weigh an average of 55-65 pounds.
  • 8 Months

When your dog gets to be around eight months old, you should have a great friendship established with them. The problem here is that they may start to get anxious when you aren’t around. This is called separation anxiety and takes a toll on your mental health. It can also take a toll on your belongings because destructive behavior usually surfaces when dogs feel this way. It’s best to have somebody with them as much as possible, so they don’t get lonely. Besides this, your dog is well on the way to adulthood, close to his final height.

  • Males weigh an average of 80-90 pounds.
  • Females weigh an average of 60- 70 pounds.

9 Months

You can expect your dog to start behaving slightly more maturely at around nine months old. This may not be true for all puppies. Still, they are calmer and are happy to behave more as long as their needs are addressed. Toys are an effective way to provide mental and physical stimulation and minimize destructive behavior. Great Pyrenees are intelligent doggies and will need mental stimulation. As they get older and their bones become more solid, they can go on hikes for exploration.

  • Males weigh an average of 85- 95pounds.
  • Females weigh an average of 65-75 pounds.

10 Months

They start listening to your commands at around ten months more than before, provided you have been consistent about their training. Now that their body is getting stronger, you can take them for longer walks. Try not to over-exert them as their bones are still developing.

  • Males weigh an average of 90- 100 pounds.
  • Females weigh an average of 70- 85 pounds.

11 Months

Homelife should be very comfortable for your dog now that they are almost one year old. Great Pyrenees are more than happy to be part of a family. You can now try to give them sixty minutes of walk time each day, split into two sessions to make it easier to manage. Try not to run with them on a leash but walk to not disrupt bone formation.

  • Males weigh an average of 95- 105 pounds.
  • Females weigh an average of 70- 90 pounds.

1 Year

It’s time to wish your dog a very happy birthday. Home life has finally settled down since they are more well-behaved now. You and your dog have both done an excellent job in training and socialization. Your dog may still act like a puppy since he is still young.

  • Males weigh an average of 100- 115 pounds.
  • Females weigh an average of 80- 95 pounds.

When Will Your Great Pyrenees Reach Its Maximum Size?

At this point, your dog is growing up nicely. You can use the standard weights and heights listed as markers, but you can always compare notes with your veterinarian to see how well your dog has grown. As long as they weren’t overfed or underfed and kept healthy throughout puppyhood, there should be no issue with their growth.

Full Grown Great Pyrenees

Your dog has done a lot of growing during his puppyhood. Male and female dogs have similar weights throughout puppyhood but differ slightly in adulthood. A full-grown male weighs around 115 pounds, while females weigh about 95 pounds. Males are also a little taller, standing around 27 inches at the shoulder, while females average 25 inches in height.

Factors To Consider

Many different factors go into your Great Pyrenees’ growth.

Understanding each can help you better understand your dog’s growth and how it may be affected. This can also provide reassurance if the growth milestones are not what you expected.

Genetics

While size is a part of their genetic line, some dogs can be larger or smaller than others. Looking at the parents can usually give you a sense of how large your dog grows, though this is only an estimation and can be way off the mark. The parents are just a small part of a giant genetic puzzle. They may have genes that result in smaller, average or larger offspring.

There is no real way to tell until your dog has reached full maturity. If you prefer, you can always ask your breeder about other offspring their dogs have produced to compare notes.

Nutrition

Nutrition is the foundation for staying healthy. This is a significant determining factor in how big or small your dog will grow. The amount of food your Pyr consumes will depend on his size, age, and energy levels. This does not mean that overfeeding your dog guarantees he will grow as large as healthily possible.

It’s important not to overfeed this breed because he will eat as much as you feed him. They already carry enough weight, so he doesn’t need more weight added to his frame. This paves the way toward obesity and may even create other orthopedic ailments. It can also lead to further health problems and add pressure to his cardiac system.

The most important consideration for his nutrition is to feed him high-quality kibble that provides a well-balanced diet. This is especially true for bigger breeds. They need a denser nutritional formula to support their growth. A well-balanced diet should involve high-quality meats, fiber, carbohydrates, healthy omega fats, vitamins, and minerals.

Growth Spurts And Plateaus

Growth spurts and plateaus can happen at any given time during your dog’s growth. This either speeds up or slows down the growing process. You cannot exactly count on these things to happen when you want to since they occur randomly. Just understand that your dog is growing at his own pace. Simply doing your best for your dog allows them to grow to their full genetic potential.

If you are wary of any changes in your puppy’s growth, it’s always best to ask a veterinarian to see if your pup is developing healthily.

Neutering And Spaying

Spaying or neutering your dog early in life does not stunt his growth. However, their joints may be affected. Some studies show that early neutering or spaying affects your dog’s growth plate. This delays its closure and may make your dog grow taller than he usually would. This can predispose them to joint disease later in their life.

Be sure to ask your veterinarian when the best time is to spay or neuter your dog. This way, they can finish their version of puberty and adequately develop.

Physical Health

Puppies who were not well for an extended time may have stunted growth. Poor health does not allow the body to reach its highest potential, so you should always check in with your veterinarian to ensure your puppy is as healthy as possible. Injury can also be a factor in the growth of a Great Pyrenees.

Please do not allow them to overexert themselves as they are growing. Always give your dog plenty of space to play so they don’t accidentally bump into anything and hurt themselves.

Frequently Asked Questions

When will my Great Pyrenees stop growing?

This breed often reaches its adult height around twelve months but continues to gain weight until two years of age.

How fast can I expect my Great Pyrenees to grow?

Your Great Pyrenees grows at a pretty steady pace, ending up larger than many other dogs.

Will my puppy experience growing pains?

Studies show that puppies do not exactly experience growing pains, but certain orthopedic conditions may give them pain. If you notice limping, swelling, a strange way of movement, and a hesitance to join normally engaging activities, something may be wrong. It’s worth going to a veterinarian to get a closer look so that you can sort out whatever is ailing your puppy. It’s also worth noting that your dog can get injured if allowed to play too rough or exercise too much.

What are some conditions common to growing Great Pyrenees?

Hip dysplasia is one common condition your dog may be predisposed to as they grow up. This is a disease where your dog’s thigh bone does not fit properly into the hip socket. This can cause a lot of pain and often leads to degenerative arthritis later in life. You can spot hip dysplasia in your dog if you notice limping, strange posture, or an unusual way of walking.

You should bring your dog to the vet when they are two years old to check if they have developed hip dysplasia. Fortunately, good breeders screen for hip dysplasia and do not allow any dogs who have it to breed. If you have received your dog from a responsible breeder, they are likely safe from hip dysplasia.

Osteosarcoma is a type of bone cancer that affects large and giant breeds like the Pyrenees. Early symptoms include lameness and leg pain. This is a painful and aggressive tumor. The sooner it is removed, the better his prognosis. If you notice your dog limping, please get in touch with your veterinarian immediately.

Great Pyrenees also suffer from Bloat or Gastric Dilation Volvulus (GDV). GDV is fatal and can be life-threatening. It is unsure why they develop this condition, but some possible ways to help prevent the onset of GDV include not overfeeding and exercising the dog before or right after a meal.

What do I do if my Great Pyrenees isn’t the correct weight?

Check with your veterinarian if you find your Great Pyrenees is not growing at a healthy pace. Numbers don’t always indicate whether your dog is a reasonable body weight. They also gain more weight as they grow older. To test if your dog is overweight or underweight, check his ribs. You should not see them, as this indicates your dog is dangerously underweight. You should be able to feel the ribs, not immediately, but by applying light pressure when pressing down on them. This must be corrected with diet and exercise. Underweight dogs need immediate veterinary assistance since they may need to be dewormed in case of internal parasites. You should consult your veterinarian for treatment plans for your overweight or underweight doggie.

Final Thoughts

Great Pyrenees are beautiful and affectionate dogs. Understanding your Great Pyrenees’ development and growth will ensure they grow healthy and happy. Getting to know the different growth factors also soothes anxieties. Our final recommendation is to bring your puppy in for his routine checkups at the vet. This way, you can closely monitor if your dog is growing to his full potential and prepare you to be a great doggy parent.
