Cavalier King Charles Spaniels are wonderful dogs. Why would anyone breed one with a mini Poodle?
Cavapoos are smarter. Poodles are known for incredible intelligence. Cavapoos tend to be smarter and easier to train than Cavaliers.
Cavapoos are hypoallergenic. Because poodles have a nonshedding coat, there’s a very good chance that a Cavapoo won’t shed or will shed minimally. The curlier the Cavapoo’s coat, the less likely to shed.
Cavapoos are healthier. Typically a hybrid dog is much healthier than a purebred, because of hybrid vigor. One of the biggest drawbacks to purebred Cavalier King Charles Spaniels is that they are prone to several health issues. In general most Cavapoo owners have found that their hybrid (Cavapoo) far outlives their purebred.
