Canine Hip Dysplasia – Collagen Related?
You will see that this topic is one that I wish for everyone, especially dog breeders to really understand. Why is this condition thought to be genetic? Is it preventable? Is it being bred out of dogs by ethical breeders?
The following is a very informative article is written by Dr. John Symes.

I have had plans to write a major paper on this frequently misunderstood topic for quite sometime. Unfortunately, the need to write about an ever-increasing number of life-threatening health issues prevented this from happening before now. But as misconceptions go, this is a high-priority item.
Hip dysplasia is not a “genetic malformation of the hip socket”, as commonly thought, but rather a weakness in the ligaments that support the hip joint. This allows the ball of this ball-in-socket joint to bang away at the joint surface, preventing the socket from forming properly. In other words, the instability created by weak supportive ligaments keeps the body from being able to manufacture a deep, smooth hip socket for the ball to fit snuggly into, resulting in the flattening of the acetabulum (hip socket) and a squaring of the femoral head (the ball). The sockets are shallow because of repetitive trauma to the developing bone (micro-fractures), which prevents the weight-bearing surface of the hip joint from forming properly. These changes worsen drastically as the cartilage covering of the joint wears away and bone-on-bone contact occurs, leaving them with the characteristic signs of the osteoarthritis we see in radiographs of affective dogs.
