Conformation shows, also referred to as breed shows, are 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. A conformation dog show is not a comparison of one dog to another but a comparison of each dog to a judge's mental image of the ideal breed type as outlined in the individual breed's breed standard. Dog show judges attempt to identify dogs who epitomize the published standards for each breed. This can be challenging, because some judgements must necessarily be subjective. As an example, what exactly entails a "full coat" or a "cheerful attitude", descriptions found in breed standards, can only be learned through experience with the breed that has that particular requirement.
