Puppy weight calculator

It's an estimate, not a measurement. This tool runs AKC's own published growth-by-percentage chart — which AKC itself labels "approximate" — backward from your puppy's current weight. Individual dogs, especially mixed breeds, can land outside the curve. Treat the number as a planning range, not a guarantee.

AKC's published checkpoints start at 6 months and run through 18 months, so predictions in that window are the most grounded in real data. Below 6 months this calculator still gives a number — interpolated back to birth rather than taken from AKC's chart — and says so; it gets noticeably more reliable once your puppy hits the 6-month mark.

Yes. Per AKC, small and medium breeds "typically stop growing by the time they reach 6 to 8 months," or around 12 months for medium breeds, while large and giant breeds keep growing until 12 to 18 months — and AKC notes some very large breeds like Mastiffs may not reach full size until 24 months. That's why this calculator asks for a size class before it does the math.

A known breed (or the breed mix on a DNA test) is the best guide. For a true unknown, AKC chief veterinarian Dr. Jerry Klein offers one hands-on check: run your hands down the rib cage — if you can still feel the "knobs" of the ribs, the puppy will likely keep growing in height. Pick the closest size class here and revisit the estimate as the shape becomes clearer.

No. Dog & Cat Translator Pro is an entertainment app: you speak or tap, and it plays bark and meow sounds back. It has no weight tracker and no growth log, and this calculator's inputs stay in your browser — nothing is sent to our servers. Use the calculator for the size estimate; use the app for a playful reply once you have it.
