Hip dysplasia is the medical term for a hip socket that doesn't fully cover the ball portion of the upper thighbone. This allows the hip joint to become partially or completely dislocated. Most people with hip dysplasia are born with the condition.
Some common symptoms of hip dysplasia include:Pain in the groin or side of the hip,A sensation of “catching” or “popping” with activity, Worsening pain with sitting, walking or running, Limping, Increased difficulty with strenuous activities. The diagnosis of canine hip dysplasia is typically made by combining: clinical signs of arthritis and pain, a complete physical exam, and radiographs (x-rays).
Canine hip dysplasia remains a problem in most large and giant breeds of dog, despite efforts to control this condition dating back to the 1960s. Because it is virtually impossible to determine the exact genotype, it is difficult to control defects like hip dysplasia that have a polygenic mode of inheritance. The best attempts at control are based on a grading scheme for identification of the defect and a breed policy of recording and publishing the results for as many dogs as possible.
