The Papillon is a toy-sized breed. Adult males typically weigh 6–10 lb (2.7–4.5 kg) and females 6–10 lb (2.7–4.5 kg). Most Papillons reach about half their adult weight around 3.2 months, hit 90% by roughly 6.7 months, and are fully grown near 9 months. Toy breeds finish growing fastest of all dogs — most of their gain happens before six months.
