Dog breed identification is deeply rooted in veterinary practice. Practice management programs, diagnostic service request forms, and government forms, including health certificates and rabies certificates, all require information on dog breed. Owners may ask for assistance in identifying the breed of newly acquired dogs, and veterinarians frequently use information regarding dog breed to assess the risk that dogs will develop various breed-specific medical problems. However, the utility of breed identification in veterinary practice may not be clear for mixed-breed dogs, particularly when parentage is unknown and must be guessed at on the basis of appearance.
