Cavapoos grow to be 9 to 14 inches (22.9 to 35.5 cm) tall when fully mature, and weigh between 7 to 25 lbs (3.2 to 11.3 kg). Male Cavapoos tend to be slightly bigger than females.
Cavapoos typically reach their full size at around 11 months, and then are more or less the same size for the rest of their lives.
There are several factors that can affect the size of an individual Cavapoo. The parents’ genes, diet, and level of exercise can play a role in determining how big Cavapoos get.
