Cavapoos typically range in size depending on the variety (Toy, Miniature, or Standard). They generally grow to be between 9 and 18 inches tall at the shoulder and weigh between 7 and 30 pounds. Toy Cavapoos are the smallest, weighing 7-14 pounds and standing 9-12 inches tall. Miniature Cavapoos weigh 10-18 pounds and are 12-14 inches tall. Standard Cavapoos are the largest, weighing 20-30 pounds and reaching about 18 inches in height. The size largely depends on the size of the Poodle parent and the dog's gender, with males generally being larger.
