Hip Dysplasia: What is it?

Hip dysplasia is a condition of the hips that may seriously affect your pet’s mobility (and your wallet). Learn more about hip dysplasia with these basic questions to better understand your pet’s risks.

What is hip dysplasia? Hip dysplasia is basically when the hip joints develop abnormally. The ball of the femur should fit perfectly into the socket (see image 1) with the support of ligaments and cartilage, and the muscles support full range of movement. With hip dysplasia, it is not a perfect fit so the bone fits somewhat loosely (see image 2) and the muscles cannot support proper movement. Typically, pets are not born with hip dysplasia, but it can later develop. Hip dysplasia may affect one or both hips.

Who does it affect? No pet is immune from hip dysplasia. All breeds of cats and dogs can get it, however dogs of larger breeds and cats with larger bones are more susceptible.

Can my pet get hip dysplasia? Hip dysplasia is believed to be genetic and is more common amongst large dog breeds such as German Shepherd Dogs, Labrador Retrievers, Great Danes, Rottweilers, Saint Bernards, and Golden Retrievers. Cats have much lower rates of hip dysplasia and it is more difficult to recognize symptoms because they weigh much less thus putting less weight on the joints. Pets with hip dysplasia in their genetic lineage are more likely to experience severe symptoms if they are obese, and also for puppies that experience rapid growth spurts.

How is it diagnosed? One symptom of hip dysplasia is pain during or after exercise. Hip dysplasia is diagnosed by a veterinarian by looking at x-rays of the hip joints. They may also be able to feel looseness in the joint. Typically, results of a hip dysplasia test are very straight forward.

How is it treated? Surgery for hip dysplasia may require a total hip replacement, or a type of joint reconstruction surgery.

How much does it cost? Total costs including x-rays, medication, and surgery can cost anywhere from $2,000 up to over $7,000.
