From what I have just be reading it seems the common thoughts are that HD might be mostly genetically predisposed but environment causes certainly have a whole lot to do with the outcome.
So my personal thoughts are that most people believe if a dog/puppy has hip problems it is immediately genetic and never there fault.
However most people do not realise that they are indeed in most case but not all; setting puppy/doggy up for these problems by improper feeding; improper exercise; improper housing!
Best thing a breeder can do is OFA, OVC or Penn Hip {or equivalent too} all breeding stock before even thinking about using them for breeding.
Best thing an owner can do is research research research!
My best friend has a 6 month old german shepherd with severe HD! She was fed and exercised properly. The parents and all through the pedigree are good or better. The vet thought perhaps puppy had been hit by a car or in some sort of accident to cause this problem!
If it is genetic and this is an honest question I would like the answer too: because BRTs are very prone to HD as well due to size:
If it is genetic where did this puppy get it from.
Father?
Mother?
Because if it was genetic then a car accident would not be the answer! The car accident might have brought it out but to be genetic it must have been an underlying issue before the accident!
Does this make sense?
It does to me but I know what I am trying to say!
I am strictly trying to learn so if something here is wrong or I have read something wrong please let me know.
At present, the strongest link to contributing factors other than genetic predisposition appears to be to rapid growth and weight gain. In a recent study done in Labrador retrievers a significant reduction in the development of clinical hip dysplasia occurred in a group of puppies fed 25% less than a control group which was allowed to eat free choice. It is likely that the laxity in the hip joints is aggravated by the rapid weight gain.
If feeding practices are altered to reduce hip dysplasia in a litter of puppies, it is probably best to use a puppy food and feed smaller quantities than to switch to an adult dog food. The calcium/phosphorous to calorie ratios in adult dog food are such that the puppy will usually end up with higher than desired total calcium or phosphorous intake by eating an adult food. This occurs because more of these foods are necessary to meet the caloric needs of puppies, even when feeding to keep the puppy thin.

When any dog has a hip dislocated, if it is not repaired within 48 hours, the socket begins to lose depth. When an injury occurs to a rear leg, whether it be a toe injury, a stifle injury, a soft tissue injury, or a hip injury, the result is often a decreased amount of weight bearing on that leg over a period of days to weeks or months. When this happens, the mechanical forces applied to the living bone tissue change, and the hips become asymmetrical, the injured hip becoming shallower in a similar fashion.
The conclusion from these observations is that the single most important environmental factor in a puppy's life is exercise, continuous and strenuous. Since this is often impossible for owners to arrange, the next considerations are to drastically restrict the diet of the growing puppy and to avoid strenuous exercise which will exhaust his muscles and leave him unable to protect his joints from injury. The puppy should be given frequent moderate exercise instead. This requires a different kind of time commitment from the owner.
