United Kennel Club is the largest all-breed performance-dog registry in the world, registering dogs from all 50 states and 25 foreign countries. Celebrating the unique Total Dog philosophy, UKC events highlight the instincts and heritage of dogs that look and perform equally well, as more than 60 percent of its annually licensed events are tests of hunting ability, training, and instinct. United Kennel Club prides itself on its family-oriented, friendly, educational events, welcoming both purebred dogs and dogs of unknown ancestry.
