Causes of hip dysplasia are considered to be multifactorial; including both hereditary and environmental factors. Rapid weight gain and growth through excessive nutritional intake may encourage the development of hip dysplasia. Mild repeated trauma causing joint lining inflammation may also be important.
Signs and Symptoms
The clinical signs of hip dysplasia are lameness, reluctance to rise or jump, shifting the weight to the forelimbs, loss of muscle mass on the rear limbs, and pain when the hips are manipulated. Dogs may show clinical signs at any stage of development of the disease, although many dogs with hip dysplasia do not show overt clinical signs. Some dogs are painful at 6 to 8 months of age but recover as they mature. As the osteoarthritis progresses with age, some dogs may show clinical signs similar to people with arthritis such as lameness after unaccustomed exercise, lameness after prolonged confinement, and worse problems if they are overweight.
Risk factors for CHD include breed (genetic), rapid growth, and nutrient excesses.
