Hip dysplasia is believed to have four contributing causes:
* genetics
* over feeding
* feeding high protein puppy formulas (especially after 6 months of age)
* too much exercise at a young age
It is felt that genetics play between a 25% and 30% role in a dog having hip dysplasia. This means that
new owners can assume a great deal of responsibility (70% to 75%) in seeing that their dog develops
good joints and hips as they are growing.
