Canine hip dysplasia (CHD) is a painful and debilitating disease where the ball and socket of the hip joint are misaligned. Hip dysplasia typically begins when the dog is young - usually starting after 4 months of age - and progresses to impaired mobility and function, and ultimately to debilitating Osteoarthritis.
Hip dysplasia is one of the most common canine orthopedic health conditions, and is a multiple gene, inherited disease.
Studies have found that large and giant breed dogs are much more susceptible to the condition - for example as many as 35% of Rottweilers and 15% of German Shepherds will suffer from hip dysplasia. Environmental factors, like a high calorie diet during a puppy's growth phase, can accelerate the underlying hip dysplasia, but do not cause it.
