Health registries maintain databases of the results of health tests for various genetic diseases or disorders, including hip dysplasia, patellar luxation, eye problems, and more. The most well known of these registries are the Orthopedic Foundation for Animals (OFA), the Canine Eye Registration Foundation (CERF), and the Canine Health Information Center (CHIC). There's also the Institute for Genetic Disease Control (GDC), which has merged with OFA but still registers eye disease and tumors separately and helps breed clubs set up registries for diseases not covered by OFA. The Josephine Deubler Genetic Disease Testing Laboratory at the University of Pennsylvania, which offers a genetic testing and counseling program for many canine hereditary diseases, has developed a Canine Genetic Disease Information System to provide information to veterinarians, breeders, researchers, and dog owners. The Canine Genetics Laboratory, Baker Institute, at Cornell University has developed DNA tests for hereditary eye disorders. These are all multibreed registries or programs, but some breed clubs have their own health registries. Reputable breeders provide proof of the parents' health certifications from one or more of these registries. You can find contact information for health registries in Appendix A.
