How this is estimated
Adult ranges come from our parent-breed size model (F1 generation). The month-by-month curve uses typical puppy growth timings: smaller dogs finish growing sooner, larger dogs later (Hawthorne et al., 2004, Journal of Nutrition; Salt et al., 2017, PLOS ONE). It's an estimate. Individual puppies vary, so ask your vet if growth seems off.
