PennHIP Radiographs
PennHIP Certification is the most reliable method available for predicting future hip osteoarthritis in dogs. At Red Sage, we offer this advanced imaging technique not only for breeders aiming to select dogs with the healthiest hips, but also for pet owners who want the best long-term joint care for their companions. Whether you're planning to breed or simply looking to identify your dog’s risk for hip dysplasia early, PennHIP provides essential insights that traditional x-rays can’t.
​
To certify your dog’s hips, we perform a quick, safe procedure under sedation. In addition to traditional hip-extended radiographs, we take specialized PennHIP views using a positioning device that allows us to obtain compression and distraction radiographs. These unique images enable radiologists to calculate a Distraction Index (DI)-- a precise measurement of how much the femoral head can move within the hip socket.
​
The lower the DI, the tighter the hips and the lower the risk for developing hip dysplasia or arthritis. This data allows for early intervention, responsible breeding decisions, and better long-term joint health for your dog.​ PennHIP radiographs must be taken by certified veterinarians, and we’re proud to offer this specialized service at Red Sage. For more information, talk to your Red Sage veterinarian or visit www.pennhip.org.
Sample report
Below is a sample PennHIP report provided to pet owners after imaging. This report shows the Distraction Index (DI) for each hip, which is used to assess the degree of joint laxity and the dog’s risk of developing hip osteoarthritis (OA).
​
In this case, the DI is 0.72-- placing the dog in the high-risk category for hip dysplasia and future OA, despite there being no current radiographic evidence of arthritis. This highlights the value of PennHIP in detecting risk before signs of disease appear, allowing for earlier, more proactive care.
PennHIP reports include:​
The Distraction Index (DI) for each hip
A breed-specific risk chart
OA risk category (low, mild, moderate, or high)
A visual summary comparing your pet's DI to the breed average
Notes on any signs of existing arthritis or other findings
