Many dogs, in particular large and giant breed dogs, have the tendency to develop hip problems. These problems are often recognized during the critical stages of a puppy's growth. However, hip problems may technically develop during any life stage, demonstrating a preference for obese dogs and senior dogs. It is generally easy to recognize hip problems in dogs because the symptoms are usually obvious. However, some dogs may be stoic and hide their discomfort.

Function
-
A dog's hips are responsible for sustaining weight and creating motion. Under normal conditions, the ball and socket structure of the hip bones fit snugly together, matching quite perfectly. In dogs with hip problems such as hip dysplasia, the ball and socket joint is loose or worse, makes no contact.
Types
-
There are various causes of hip problems in dogs. The dog may have sustained an injury such as a sprain, a dislocation or a fracture. Among inherited hip problems, hip dysplasia and osteocondrosis are common in large dogs, while small dogs may suffer from Legg-Perthes disease. Another possibility, especially in obese and senior dogs, is arthritis.
Symptoms
-
When the hip area is affected, dogs develop symptoms such as: limping, swelling, difficulty climbing stairs, a typical ''bunny hop'' gait, pain upon getting up, pain upon flexing and extending the joint and muscle atrophy in the rump area.
Diagnosis
-
Suspected cases of hip problems should be evaluated by a veterinarian, who may provide a diagnosis. Diagnosis is generally confirmed by extending and flexing the joint, by assessing the range of motion and by taking x-rays.
Treatment
-
Treatment is based on diagnosis. Obese dogs are put on dietary programs, hereditary conditions are often corrected surgically, injured dogs are given pain relievers and rest, and dogs with arthritis may be prescribed NSAID's or supplements such as Glucosamine.
