CERF Examination CERF (Canine Eye Registration Foundation) examinations are performed at the request of an owner, breeder or veterinarian to evaluate dogs for inherited eye diseases. The Canine Eye Registration Foundation was founded in an attempt to decrease the incidence of genetic eye conditions in purebred dogs. Dogs that are free of such eye disease are given a CERF number that appears on the AKC papers.  WEB SITES OF INTEREST TO BREEDERS Canine Eye Registration Foundation (CERF) Institute for genetic disease control (GDC) Optigen - Genetic testing for Inherited Eye Diseases of Purebred Dogs CANINE BREED CLUBS and RELATED GROUPS American Kennel Club LOCAL BREEDERS and KENNELS English Springer Spaniel Website design by HYPERSPHERE ©2005 Animal Eye Care.
