At what age are animals typically evaluated for hip dysplasia by the OFA?

Hip dysplasia evaluations are typically recommended by the Orthopedic Foundation for Animals (OFA) at the age of 2 years. This timing is significant because hip dysplasia is a hereditary condition that can manifest and develop over time. Animals evaluated earlier than 2 years may not display the full extent of the condition since the joint and surrounding structures may still be undergoing changes and maturation. Evaluating at 2 years allows for a more reliable assessment of the hips, as this age accounts for the growth and development of the skeletal system, giving a clearer view of any abnormalities. This age benchmark helps breeders and veterinarians make informed decisions regarding breeding practices and the management of affected animals.
