The progression of hip dysplasia was investigated in 116 military working dogs. Medical records were reviewed for any clinical history of hind-limb lameness. Pelvic radiographs were studied for evidence and degree of hip dysplasia, degenerative joint disease, or both. The number of months each dog worked was determined. Each dog's age at termination from service and cause of death (or euthanasia) were recorded. The mean months of work for normal and dysplastic dogs were evaluated using the Student's t-test. No significant difference was found in the total number of months worked between normal and dysplastic dogs (p greater than 0.05).
对116只军犬的髋关节发育不良进展情况进行了调查。查阅医疗记录以了解后肢跛行的任何临床病史。研究骨盆X光片以确定髋关节发育不良、退行性关节病或两者的证据及程度。确定每只狗工作的月数。记录每只狗退役时的年龄及死亡（或安乐死）原因。使用学生t检验评估正常和发育不良犬的平均工作月数。正常犬和发育不良犬的总工作月数未发现显著差异（p大于0.05）。
