How the Puppy Growth Rate Calculator works
Methodology
Weekly change = (current weight − previous weight) ÷ days × 7. Percentage change uses the previous weight as the baseline.
Frequently asked questions
Should a puppy gain the same amount every week?+
No. Growth is not perfectly linear and varies by breed, age and health.
Important veterinary note
Calculator outputs are estimates for education and planning. They do not diagnose disease, replace a physical examination, or override advice from a veterinarian who knows your dog.
