Hips of the Golden and Labrador retrievers in Korea were evaluated with the University of Pennsylvania Hip Improvement Program (PennHIP) and the severity of joint laxity and degenerative joint disease (DJD) were compared to the PennHIP database. The distraction index (DI) of domestic Golden and Labrador retrievers was significantly higher than the DI of the PennHIP database. In the two breeds, the prevalence of DJD increased according to the DI. However, the severity of DJD did not show a positive correlation with the DI. Overweight dogs and dogs kept indoors showed more severe DJD and more prevalence of clinical signs. This report is thought to be the first case presentation of a large population of Golden and Labrador retrievers in Korea and the findings are representing the overall level of canine hip dysplasia (CHD) of domestic Retrievers, as the PennHIP method was not available in Korea until 2001. We can respect that the stock of retrievers can have a tighter hip joint through control of CHD using an accurate diagnostic method keyed to a phenotype especially concern for joint laxity using PennHIP method and an organized screening program. The clinical manifestation of dysplastic dog can be reduced through control of bodyweight and the environment with regular monitoring the hips with concern for joint laxity using PennHIP method.
