Puppy growth charts by breed
Pick a breed to see its growth chart, with puppy weight by month from 8 weeks to 1 year, and to run the calculator with that breed already set. Charts for 9 popular breeds from the AKC’s 2025 ranking sit on growth curves fitted to published studies. 11 more breeds are listed below without a chart yet: their size classes still use estimated curves.

Each breed sits in the size class of the middle of its AKC range, or of its top weight when the AKC gives only an upper value. The five classes come from a 2023 study of dog life expectancy (Montoya et al.). Some ranges cross a class line, and each breed page says so.
