Hip Dysplasia is a condition that can sometimes cause concern to breeders and owners of larger types of dogs as it can be hereditary. Dogs more prone to Hip Dysplasia include alsations, retrievers, great danes, saint bernards, german shepherds and rottweilers. It can also be found in other types of dogs though rarely in smaller breeds.

Before discussing the causes, what are the signs to watch for that might warn of this condition developing and at what time in the dog's life might this condition show?

Although similar to symptoms of arthritis, this is not a condition that occurs just in older dogs. Puppies can be subject to Hip Dysplasia but generally it is seen in middle aged and older dogs.

Dogs with this condition may at first show signs of stiffness and lameness. An X-ray examination might show that the head of the femur (the long bone of the leg) is malformed so will not fit into the socket of the pelvic bone.

Generally the symptoms to watch for if you suspect your dog might be suffering from Hip Dysplasia are:

* Changes in the way he runs or walks for instance a slight limp from the hip area

* Signs of pain and stiffness in the rear legs first thing in the morning and during exercise

* Reluctance to join in normal activities

As the condition worsens, the limping will be more obvious, the dog will be in pain showing difficulty when trying to lie down, stand up and on walking. There may also be distress when people stroke his hips and generally the dog will become less active.

What Might Cause Hip Dysplasia?

There are a number of known reasons why a dog might develop Hip Dysplasia and research continues into this condition. One recognised cause is genetics. It has been found that when dogs with Hip Dysplasia are bred, their puppies have a high chance of inheriting the disease. Even those puppies that don't develop Hip Dysplasia could be carriers which means that they could pass it on to their offspring.

Nutrition and Hip Dysplasia

It has also been established that over-weight dogs are more prone to developing this condition. The ball and socket joints in the hips of obese dogs can sometimes grow apart, leading to this painful disease.

A lack of calcium and low levels of protein in the diet can bring about Hip Dysplasia. Calcium is necessary to keep bones healthy and without this in the diet, bones will weaken and become deformed. Protein helps build muscles and good muscles will help keep the hip joints working well.

Hip Dysplasia is chiefly a disease in pedigree dogs although it can occur in mixed breeds, mostly when this is a cross of two dogs already prone to developing the condition.

If early signs of Hip Dysplasia are caught in time, owners and veterinarians can work towards helping to relieve the pain through medical management. Surgical options are also available depending on the severity of the condition.
