What is a measure of breed laxity in dogs as per PennHIP?

The measure of breed laxity in dogs as per PennHIP is known as breed laxity ranking. This ranking is a specific evaluation within the PennHIP method, which assesses hip joint laxity as a predictor for the likelihood of developing hip dysplasia. The measurement focuses on how loose the hip joint is, which can significantly influence a dog's risk for future joint issues.

PennHIP utilizes radiographic images and specific angles to quantify how much laxity is present in the hip joint. By establishing a breed laxity ranking, veterinarians and breeders can make more informed decisions about breeding practices, aiming to reduce the prevalence of hip dysplasia in certain breeds. This ranking is particularly valuable in helping to determine the heritability of hip laxity and its impact on canine health across various breeds.
