Registries

• Closed registries release only normal results to the public.

  • PennHIP and Canine Eye Registration Foundation (CERF) are examples of closed registries.
  • Orthopedic Foundation for Animals (OFA) was a closed registry, originally.
  • Now OFA is a semi-closed registry. All normal results are still released, but abnormal results will only be released to the public with owner consent.

• Open registries would provide information on normals, affected and carriers.

• OFA (hip, thyroid, pra, heart, sebaceous adentitis, etc.)

• PennHIP

• CHIC - The Canine Health Information Center, also known as CHIC, is a centralized canine health database jointly sponsored by the AKC/Canine Health Foundation (AKC/CHF) and the Orthopedic Foundation for Animals (OFA) For more information, the SCA CHIC liaison is Carla Barstow
