A Cavapoo is a Poodle hybrid that is a cross-breed of a Poodle and a Cavalier King Charles Spaniel and may demonstrate any combination of traits from those two breeds. Poodle hybrids have become very popular in the past few years. They play a big role in the current designer dog trend. The cross with the Poodle is usually because of the Poodle's nonshedding coat. The experimentation of these hybrid or designer dogs has not been recognized by the American Kennel Club or Canadian Kennel Club. The key to cross breeding to purebred dogs is what is called hybrid vigor, the breeding resulting in a healthier dog with superior genetic constitution can come from dogs purebred for so long that they have common genetic disorders.
