How it works
Puppies reach about 50% of adult weight at around 4-5 months for small breeds, 5-6 months for medium, 6-7 months for large and 8-9 months for giant breeds. The estimate divides current weight by the typical fraction of adult weight for that age. Genetics vary - treat it as a rough guide.
FAQ
