This paper is a refinement of previous studies in that only suitably radiographed dogs were included in the data base. The rate of hip dysplasia varied widely by breed from five percent in siberian huskies to eighty-three percent in english bulldogs. There was a significant difference in the prevalence of dysplasia within at least two breeds; golden retrievers and old english sheepdogs. Physical size per se did not appear to be an important determinant of hip dysplasia.
本文是对先前研究的细化，因为数据库中仅纳入了经适当X光检查的犬只。髋关节发育不良的发生率因品种而异，差异很大，从西伯利亚哈士奇的5%到英国斗牛犬的83%不等。至少有两个品种（金毛寻回犬和古代英国牧羊犬）的发育不良患病率存在显著差异。体型本身似乎并不是髋关节发育不良的重要决定因素。
