Weight & Age Calculators

Healthy weight, real age and adult size.

Is your dog a healthy weight? How old are they really? And how big will that puppy get? Three quick, vet-informed answers — and you can save them to your dog.

Body condition score (optional, 1–9)

1 = too thin4–5 = ideal9 = overweight

How we calculate this (and why “×7” is a myth)

Healthy weight uses each breed’s standard adult range, refined by a 9-point body-condition score (4–5 is ideal). Dog-years uses the peer-reviewed epigenetic-clock formula — 16 × ln(age) + 31 — which is why a 1-year-old dog is closer to 31 in human terms than 7. Puppy growth compares your dog’s current weight to a typical size-class growth curve.

Educational estimates based on breed averages and population research — every dog is an individual, and this is not a diagnosis or a substitute for your veterinarian.
