How Big Are Great Pyrenees Compared to Other Breeds?

Great Pyrenees are on par with other very large breeds such as the Saint Bernard and the Mastiff in terms of size, easily dwarfing medium-sized dogs like the Border Collie and the Siberian Husky. They share the physical robustness and imposing presence of the Newfoundland, yet they are distinctively known for their thick, white coats and calm, protective demeanor. While their size and strength were originally valued for guarding livestock against predators in mountainous regions, in a family setting, these traits translate to a gentle yet vigilant companion. The Great Pyrenees represents the upper echelon of canine size, requiring ample space and consistent training to thrive as both working dogs and family pets.

How Much Variation in Size Is There Amongst Different Great Pyrenees?

Variation in size among Great Pyrenees can be notable, primarily due to gender differences, with males generally being larger than females. Additionally, individual genetics and breeding purposes (working vs. show lines) can influence size.

To assess if a Great Pyrenees is at a healthy weight, you should be able to feel their ribs with a slight fat covering; they should not be visible. A defined waist should be noticeable from above, and the abdomen should be visibly tucked up from the side. Given their dense coat, it might be easier to check their weight by feeling rather than visual inspection. Maintaining a healthy weight is crucial for preventing joint and health issues in such large breeds.

When do Great Pyreneess Stop Growing?

Most Great Pyrenees will reach their full height by 1 to 1.5 years of age. However, they might not be fully grown in terms of weight and muscle mass until they are 2 to 3 years old. The period between 1.5 to 3 years is when they fill out, gaining muscle and achieving their full adult structure.

For the initial months, the growth of a Great Pyrenees puppy can be quite rapid. By the age of 6 months, they would have reached a significant portion of their adult size, but they are not fully grown yet. Between 6 months and a year, their growth rate might slow down a bit, but they will continue to grow in size, especially in terms of their weight and bone density.

Can You Predict the Size of Great Pyrenees When it is a Puppy?

Predicting the exact size of a Great Pyrenees when it is fully grown based solely on its size as a puppy can be challenging. However, there are some indicators. Observing the size of the puppy’s paws can give a hint; large paws often suggest a larger adult dog. Additionally, looking at the size and weight of the puppy’s parents can provide a ballpark estimate.
