Great Pyrenees puppy growth: milestones and weight estimates
How fast a Great Pyrenees puppy grows, illustrative weight estimates and the limits of predicting adult size.
Growth is a long, slow process. Puppies can gain 2 kg or more a week at their peak, reach most of their height by around 12 months, then spend another year filling out. Many don't look or act fully adult until 2 years, and some males keep broadening until nearly 3.
A large-breed puppy food, fed in measured amounts, keeps growth steady rather than rapid, which is kinder to developing hips and elbows. Keep the puppy lean with a visible waist, avoid forced running and long stair sessions, and let it rest when it lies down on a walk. Limping, a bunny-hopping gait or pain when getting up are reasons to book a vet visit rather than waiting it out.
