Estimates combine your puppy’s current trajectory with typical growth curves for this breed and size class. Individual dogs vary — nutrition, genetics and neuter timing all matter. For health concerns, ask your vet.
The American Foxhound is a medium-sized breed. Adult males typically weigh 65–70 lb (29.5–31.8 kg) and females 60–65 lb (27.2–29.5 kg). Most American Foxhounds reach about half their adult weight around 4.3 months, hit 90% by roughly 9.1 months, and are fully grown near 13 months. A useful rule of thumb for medium breeds: they roughly double their four-month weight.
