breed standards

Ideal specimen criteria

Breed standards are the official specifications defining the ideal characteristics of a dog, cat, or other purebred animal—covering physical traits like size, coat, coloring, and proportions, as well as temperament.

Kennel clubs and breed registries establish these standards, and judges at shows evaluate animals against them: The dog was disqualified for not meeting breed standards.

Breeders use standards as blueprints when selecting which animals to mate.
