Great Pyrenees Owner Guide
Great Pyrenees growth chart and weight by age
TL;DR
Use a Great Pyrenees growth chart as a loose reference, not a target to hit. These are large, slow-maturing dogs: height can slow before the body has fully filled out, and healthy littermates can follow different curves.
- AKC lists adult height at 27–32 inches for males and 25–29 inches for females; the standard describes weight as proportionate to overall size and structure.
- Track your puppy’s own trend, food, body condition, appetite, stool, and activity with your veterinary team.
- Do not try to maximize growth or correct a chart mismatch by overfeeding.
| Sex | AKC height at withers | Weight guidance |
|---|---|---|
| Male | 27–32 inches | About 100 lb at 27 inches; proportionate to structure |
| Female | 25–29 inches | About 85 lb at 25 inches; proportionate to structure |
Those are adult reference points, not a month-by-month prescription. Genetics, sex, litter size, food, and health all influence an individual puppy’s pace.
| Age | Useful focus | Avoid assuming |
|---|---|---|
| 8–16 weeks | Steady meals, weekly trend weights, socialization and safe rest | Two same-age pups should weigh the same |
| 4–6 months | Teething, body condition, gentle handling and movement | A tall puppy is automatically overweight |
| 6–12 months | Adolescence, nutrition review, training consistency | Near-adult height equals mature joints |
| 12–24 months | Gradual conditioning and adult-life routines | Filling out stops as soon as height slows |
Rapid loss of weight, poor appetite, repeated vomiting or diarrhea, lameness, pain, lethargy, or a sudden body change deserves veterinary advice. A body condition assessment is more informative than internet comparison photos. For a giant-breed puppy, ask about an appropriate complete diet and a growth plan tailored to the individual dog.

- Height often slows before the dog finishes filling out. Many continue maturing through the second year and sometimes beyond; individual timelines vary.
- How much should a Great Pyrenees puppy weigh?
- There is no single safe target for every age. Use breed references only as context and follow your own puppy’s steady trend and veterinary body-condition assessments.
