How to Help Your Dog Prepare for Hip Dysplasia
Canine Hip Dysplasia is probably the most common inherited orthopedic disease in dogs. Animals with this disease develop stiffness in their joints, arthritis pain, and difficulty getting around. There’s no cure for the disease, but breeding dogs can be screened to make sure puppies are less likely to have dysplasia. For non-breeding dogs that are susceptible, screening helps owners plan for palliative care early on, before their pet develops clinical signs.
The best screening test is called PennHIP, and it uses three radiographic scans of the hip joints to determine a dog’s dysplasia risk. The first scan is a conventionally extended hip radiograph (similar to the OFA method), which looks for existing arthritic changes. This view alone cannot reliably distinguish between “normal” and disease-susceptible dogs. What this means is that if your dog is “normal” at 2 years of age, your dog could still develop hip dysplasia later on in life but there is no way to know if only this one radiographic view is used.
The two additional scans are called compression and distraction radiographs. These get taken while the dog is in a neutral weight-bearing orientation. The vet will analyze these scans for indications that the hip joints have excess laxity. This laxity is measured and then expressed as a number known as the Distraction Index (DI). The degree of laxity represented by this Distraction Index number can be ranked among other dogs within the same breed. For breeders, this means they can choose to breed with dogs that have tighter hips (a lower DI number) than theirs, in order to cancel out the possibility that offspring will develop dysplasia.
For non-breeding dogs, knowing if your pet is susceptible to developing hip dysplasia can help in developing an early strategy of diet, appropriate exercises and supplements which may delay or diminish the onset of the disease.
