Twenty-plus years ago, I began competing in dog shows and trials. This hobby changed my life. Want to find out how to have fun with your dog, live with a mannerly dog, or what resources are out there for mixed as well as purebreds?

KENNEL CLUBS
Purebred Registries:
United Kennel Club (registers more breeds than AKC)
National Kennel Club
Canadian Kennel Club

Mix Breed Registries: Aside from some mix breeds becoming popular enough to possibly become “breeds” of their own, these registries provide a place for the mix breed to compete in obedience, agility, and an assortment of sports for dogs.
