Hip dysplasia is the abnormal development and growth of a dog’s hip joint. It has been reported in Border Terriers. Some dogs have presented with severe lameness. Canine hip dysplasia (CHD) is a complex disease with a high environmental component associated with the expression of lameness. Inheritance is complex with multiple genes contributing to the expression of CHD. Responsible breeders evaluate the hip status of dogs, as well as their siblings and parents, when making selections on breeding pairs. In Sweden hip scores are required for registration. Where breeders have selected for better scores there has been an improvement in total scores. Unfortunately, in the US not all hip results are entered into the OFA Open database.
