The Cockapoo is a small breed. Adult males typically weigh 12–25 lb (5.4–11.3 kg) and females 10–22 lb (4.5–10.0 kg). Most Cockapoos reach about half their adult weight around 3.8 months, hit 90% by roughly 7.9 months, and are fully grown near 11 months. Small breeds do the bulk of their growing in the first six months, then fill out slowly.
