When do Cockapoos stop growing?

A Cockapoo will usually stop growing by the time they are one year old. They will typically reach their adult height by the time they’re nine months old but don’t stop growing until their first birthday. Because a Cockapoo is a “designer dog,” they come in four different types: Teacup, Toy, Miniature, and Standard. Depending on the type of Cockapoo, the dog can grow to a variety of sizes.
