About Me
Built by dog owners, for dog owners. Here’s everything about who we are, where our data comes from, and why you can trust our calculators.
Our Mission
WeightMyDog exists to give every dog owner free, accurate, and easy-to-understand information about their dog’s weight and growth without paywalls, subscriptions, or confusing jargon.
We believe that knowing whether your dog is at a healthy weight shouldn’t require a vet visit or expensive app subscription. Every dog owner deserves access to the same data that professional breeders and veterinarians use — and that’s exactly what we provide.
How We Build Our Calculators
Every weight calculator on WeightMyDog is built using a multi-source data methodology:
- Primary source: Official AKC breed standard weight specifications for every recognised breed
- Secondary source: AVMA veterinary growth guidelines and body condition scoring standards
- Tertiary source: Published canine growth research from peer-reviewed veterinary journals
- Validation: All calculators are reviewed by a qualified veterinary professional before publishing
Growth charts are built from actual growth curve data, not simple linear interpolations. This means our week-by-week estimates reflect how dogs actually grow — with faster early growth that plateaus as they approach adult size.
