This study was carried out to estimate the range of the hip score with 3 radiographic evaluation techniques and to identify the relationship among these methods in 71 Sapsarees (35 males and 36 females). Mean age of dogs was ranged from 4 to 73 months (averaged months). Hip joints were evaluated with OFA method, BVA/KC scoring scheme, and method. Hip joints were graded by the OFA grading system(only used for dogs over 24 month old age). The 64 joints evaluated were graded as good (17.2%), fair (46.9%), mild dysplastic (12.5%), moderate dysplastic (7.8%), and severe dysplastic (15.6%), respectively. In BVA/KC scoring scheme, the mean score of the 86 joints was recorded as (range from 2 to 52). The mean of Norberg angle in the 78 joints was degree (ranged from 63 to 110.5 degree). In method on the 126 joints, the mean DI was resulted as (ranged from 0.08 to 1.0). BVA/KC scores were gradually increased with age, positively correlated with OFA grade (r = 0.92, P < 0.001), but inversely proportional to Norberg angle (r = -0.79, P < 0.001). However, there was no correlation between BVA/KC and DI (r = 0.11). It was suggested that Sapsarees have high prevalence of cannine hip dysplasia, so selective breeding among sapsarees having normal hip joints might be necessary for preventing or controlling hip dysplasia.
