A dog show is an animal show; it is an event where dogs are exhibited. A conformation show, also referred to as a breed show, is a kind of dog show in which a judge, familiar with a specific dog breed, evaluates individual purebred dogs for how well the dogs conform to the established breed type for their breed, as described in a breed's individual breed standard.
Dog shows can be in the means of evaluating dogs for breeding purposes. A conformation championship from a recognised national kennel club is generally considered as an indication of merit. Many breeders consider championships a prerequisite for breeding.
