What Is PennHIP?
PennHIP (Penn Hip Improvement Program) is an advanced method for evaluating hip health in dogs and assessing their risk for developing hip dysplasia. Compared with traditional OFA screening and standard hip X-rays, PennHIP provides a more objective measurement of hip laxity (looseness) and can identify dogs at higher risk for hip dysplasia earlier in life.
Hip dysplasia is one of the most common orthopedic conditions in dogs, particularly in larger breeds. When the hip joint does not fit together properly, it can lead to pain, arthritis, and reduced mobility over time. PennHIP helps detect potential issues before arthritis or discomfort develops, allowing for earlier intervention and informed decisions about your dog's long-term orthopedic health.
How the PennHIP Evaluation Works
PennHIP uses a series of specialized radiographs (X-rays), precise positioning techniques, and mathematical analysis to evaluate hip stability more accurately than traditional screening methods. The procedure includes three specific X-ray views that measure hip joint laxity and assess overall hip function.
Because proper positioning is essential for accurate results, dogs are typically placed under light sedation or anesthesia to ensure comfort and allow the images to meet PennHIP's strict standards.
The radiographs are submitted to certified PennHIP analysts, who calculate a Distraction Index (DI) score that helps determine your dog's risk of developing hip dysplasia later in life.
Benefits of PennHIP
One of the biggest advantages of PennHIP is that evaluations can be performed in dogs as young as 16 weeks (4 months) of age. This early screening allows veterinarians and pet owners to take proactive steps before significant joint damage occurs.
PennHIP offers several benefits, including:
- Earlier detection of hip laxity and potential hip dysplasia
- More accurate assessment of future arthritis risk
- Objective scoring for greater consistency
- The ability to screen dogs at a younger age
- Valuable information for breeders, working dog owners, and pet owners
- Guidance for preventive care and long-term joint health planning
Based on the results, veterinarians may recommend weight management, exercise modifications, muscle support, joint supplements, ongoing monitoring, or additional orthopedic care to help slow the progression of joint disease and support lifelong mobility.
When to Schedule a PennHIP Evaluation
PennHIP evaluations can be beneficial for dogs of any breed but are especially recommended for breeds with a higher risk of hip dysplasia. The evaluation is commonly used by breeders when making breeding decisions and by owners who want a better understanding of their dog's future orthopedic health.
At our hospital, PennHIP evaluations are performed by certified veterinarians who have completed the required PennHIP training. If you would like to learn more about whether your dog is a candidate for PennHIP screening, our team would be happy to help.
