HD & CsV

Interesting. This means we are indeed far from knowing about HD in wolves.

Other protective element:

"Hip dysplasia has not been reported in the wild undomesticated carnivorous animals, such as wolves and foxes. A study of their pattern of growth found that the pups were slow-growing and late maturing. The young pups were whelped in dens. As newborns, they received their nourishment by nursing during the first few weeks. When more food was required, the mother killed rodents and either brought them to the den or ate the animal where it was killed and then returned to the den where the ingested rodents were regurgitated for the young to eat.(61) Young carnivores were quite mature and 6 to 10 months old before they began to hunt. The amount of food available for the growing members of a litter was limited. This caused the young to mature slowly and remain thin and light for their body size. Such an environment favored the completion of ossification and developmental maturity of the joint before the hips could be subjected to possible injury, incongruity, or subluxation from excessive extrinsic forces (e.g., excessive body weight) (65,69)"

... but this protective way of living doesn't mean free HD-gene carrier.

That´s the point. There is no dog breed 100% free of HD and all dogs are descendents of wolf. It can be a mutation but the breeds developed on very different places.

I think I read about examinations they made in the US on wolves (it might have been in Yellowstone National Park), which were killed (by cars) - and they found some wolves which had HD. It is a while ago, that I read it, so I do not know the source any more - but maybe I can find out.

I have also read about wolves whit HD, I think it was a Timber Wolf...

But I think it is very unusual, and it is also hard to know if this wolf had
food enough as a pup to develop a good bone structure...

But I´am no expert on this subject area, and do not know exactly how
much the food influence on the development of HD.

Is it possible to develop HD even if it is not inherit from the parents,
only by bad food or no food ???

I know a link on the other direction, too much food => high growth rate => more risk for HD and ED.
