Here's why:
* Size: Miniature Poodles are a good size match for Cocker Spaniels, resulting in Cockapoos that are typically around 10-15 inches tall.
* Temperament: Miniature Poodles are known for being intelligent, playful, and affectionate, traits that often carry over to Cockapoos.
* Coat: While both standard and miniature Poodles have hypoallergenic coats, miniature Poodles tend to have a slightly less dense coat, which can make Cockapoos slightly less hypoallergenic but easier to manage.
While it's possible to breed a Cockapoo with a standard Poodle, it will result in a larger dog, and might not be as common.
