OFA = Orthopedic Foundation for Animals.

X-rays are taken of your dog's hips and elbows. Then a panel of 5 Veterinary Radiologists review those pictures for genetic/hereditary defects that could be passed on through breeding.

With these certifications, I can feel assured that if I breed Casey someday, that he will not pass along any genetic defects to his offspring. ANY ethical breeding should include OFA for hips and elbows as well as CERF for eyes for both parents.
