Consider surgery to relieve your dog's pain, if your vet suggests it. A total hip replacement is a common treatment for hip dysplasia. This surgery has very good results, as both parts of the hip joint are replaced with artificial parts that move smoothly. Depending on the age and weight of your dog, other options are available, such as FHO (femoral head ostectomy). In this procedure, the ball is removed from the head of the femur, or leg bone, which eliminates friction from the ball and socket rubbing together. Scar tissue and muscle will create a pseudo joint so they leg can move freely after the recovery period.
