The dog breed Cavapoo is usually full grown by the time they reach 8 to 9 months of age.
Once they get to a year old the Cavapoo will no longer grow anymore than what it currently is in size.
The Cavapoo is also known as a Cavoodle which is a crossbreed dog and is the offspring of a Poodle and a Cavalier King Charles Spaniel.
This dog breed is a small dog breed so they won't get very big so once they reach 8 months of age they are likely already fully grown.
Cavapoo dogs are small dogs and will weigh anywhere up to 20 pounds, and 12 – 14 inches tall.
They are a very loving and easy dog to take care of and are good around kids as well.
