One of the most common joint ailments that affect dogs is hip dysplasia which develops when the joint develops abnormally in young dogs and can affect either one or both hips. This disorder can be caused by a number of factors including genetic factors, ageing, disease and injury which can lead to a loosening of the joints, muscles, cartilage or connective tissues causing the leg bones to move further apart and weakening the joint capsule and ligament.

With the weakening of the joint capsule and ligament the entire joint becomes unstable and over time the damage can lead to arthritis in the affected joint, resulting in pain and limited movement. Large and giant breeds such as German Shepherds, Golden Retrievers, Rottweilers and Great Danes are more likely to develop hip dysplasia with purebred dogs affected more often.

Usually, a dog with hip dysplasia will be in obvious pain or discomfort during and after vigorous exercise, and eventually during normal daily activities. Affected dogs may also walk with a stiff or irregular gait and as the disease progresses, may voluntarily limit their activity. If left untreated, the dog may be unable to walk within a year or two.

Often these symptoms are considered a normal sign of ageing, but a physical examination and x-rays will provide a definitive diagnosis. Treatment can be in the form of several types of surgery depending on the dogs age, health and the damage to the hips. Usually Anti-inflammatory and pain relief medications are also prescribed in combination with supplements to help re-grow the cartilage.
