Getting Connected: RFGS/BOAS Info & List

General Information: RFGS/BOAS Certification with OFA

Cost

OFA registration is required for all exam participants. The OFA registration fee is $15. The RFGS veterinary exams are priced separately, and the fee is determined individually by the examining veterinarian.

Release of Exam Results

All exam results are recorded in the OFA database and shared with the international team of researchers and collaborators at the University of Cambridge for statistical purposes.
Dogs receiving Grades 0 or I are considered clinically unaffected by BOAS, and will received OFA certification numbers. Results for Grades 0 and I are released by default and are posted on the OFA website. Grade II and III results are only released IF the owner authorizes release of the results.

Minimum Age, Repeat Exams, Breed Eligibility

The screening program is currently open to Pugs, Bulldogs, and French Bulldogs. Other brachycephalic breeds can participate in the exams, however they are ineligible at this time for certification.The minimum age for RFGS testing is 12 months. Exams on dogs under 12 months of age are considered preliminary and are ineligible for certification.While recertification is not required, if the dog is under 24 months of age at the time of the examination it is recommended that they have annual veterinary health checks as BOAS can develop later in life.

Exam Availability

Any approved examiner can perform the RFGS at their veterinary practice, or in their teaching hospital if in an academic setting. Appointments should be made directly through the examiner or their staff.Exams may also be offered in clinic setting such as health clinics sponsored by dog clubs. The OFA must approve these events, and they can be found on the OFA’s Health Clinic Calendar at: https://ofa.org/health-clinics/Inquiries from clubs interested in organizing a RFGS screening event should be addressed to the OFA at: ofa@offa.org. The following RFGS Clinic Planning Guidelines will help the organizers plan a successful clinic.
