Certain breeds are more prone to it.
Does it happen with Coonhounds? Yes. But not like breeds such as Labs and etc...Every once in a while you will hear about a Coonhound with it.
Here is the latest stats (through 2011) off of OFA's site:
http://www.offa.org/stats_hip.htmlMy opinion is I think that down the road it will be more common within the Coonhound breed. With the rise of the net and all these forums and classifieds, folks have a greater way to sell pups than before the net existed.
Coonhound folks breeding that shouldn't be breeding are breeding because they have a male and female dog. More and more no count Coonhounds with genetic faults are polluting the gene pool because so and so can make some $$$.
The #'s you posted are only for dogs that have tested..............I would venture to say that I would guess when your talking #'s, that the OFA #'s represent less than 1% of overall dog population.
Now those # make you stop and think. Take the Bulldog - 506 evaluations over the last 37 years -- 72.1% of the 506 evaluations has some form of Dysplasia.
Who are the ones paying to test? It is not the backyard breeders or puppy mills. I would venture to say that it's well respected breeders who make planned crosses with other well known dogs (especially in the show dog world) where pedigrees are studied and scrutinized to produce the best dogs.
If the #'s for those type of dogs are at 72.1%, then does that correlate back in the untested dog world of the backyard breeders and puppy mills of Bulldogs with issues with Dysplasia?
I would say that yes..........which my reasoning above on Coonhounds down the road will have the issue with the way folks are breeding no count dogs like the other breeds have been bred to no count dogs with genetic faults and look where we are today with alot of the different breeds and the health problems with breeds.
