Is Your Dog at Risk for Hip Problems Later in Life
Hip problems are one of the most common issues dogs face as they get older — especially in larger breeds. The good news is that with the right testing, you can find out early and take action before things get worse. At Dorset Street Animal Hospital, we offer PennHIP testing to help you understand your dog's hip health and plan ahead.
What is PennHIP Testing
PennHIP stands for Pennsylvania Hip Improvement Program. It's a scientifically developed method of evaluating a dog's hip joints using X-rays. Unlike a standard hip X-ray, PennHIP uses a specific technique that gives a much more accurate picture of how loose or tight a dog's hip joints are.
This matters because loose hips are one of the main reasons dogs develop hip osteoarthritis (OA) or canine hip dysplasia (CHD) as they age. The looser the hip joint, the higher the risk.
PennHIP testing gives a score called a Distraction Index (DI) — a number between 0 and 1 that reflects how much the hip joint moves. The lower the number, the tighter (and healthier) the hip. Your vet uses this score to assess your dog's risk and guide next steps.

What is Hip Dysplasia in Dogs
Canine hip dysplasia (CHD) is a condition where the hip joint doesn't develop properly, causing the ball and socket to rub and grind instead of moving smoothly. Over time, this leads to pain, stiffness, and a condition called hip osteoarthritis (OA).
It's one of the most common skeletal conditions in dogs and can significantly affect their quality of life — especially in working dogs, service dogs, and active breeds. Some dogs show signs early, but many don't show obvious symptoms until the damage is already done. That's why early testing is so valuable.
Does Your Canine Companion Need PennHIP Testing
PennHIP testing is a great idea for:
- Puppies as young as 16 weeks: especially large or giant breeds prone to hip issues
- Working dogs and service dogs: early detection can help extend their working life
- Breeding dogs: to make responsible breeding decisions and reduce the risk of passing on hip problems
- Active or athletic dogs: to ensure their hips can handle the demands placed on them
- Any dog owner who wants peace of mind about their dog's long-term joint health
Breeds commonly tested include German Shepherds, Labrador Retrievers, Golden Retrievers, Rottweilers, and other large breeds — though any dog can benefit from the screening.
