What Is WeightMyDog?
WeightMyDog is a free dog weight calculator built for owners who want real answers — not guesswork. Most online tools give you a generic chart. WeightMyDog gives you breed-specific predictions built on AKC adult weight standards, verified growth formulas, and AVMA veterinary guidelines.
Whether you have a 10-week-old French Bulldog puppy or a 2-year-old Great Dane, WeightMyDog tells you whether your dog is on track, flags weight concerns early, and gives you a concrete feeding plan — all instantly, all free.
Built by Mitchell Aldwell after years researching canine growth patterns across 500+ breeds. Every calculator is independently tested.
