Some of the inbreeding stuff seemed really extreme but maybe that is a UK problem? Or maybe more common in other breeds?
I'm afraid not. I know a few people who work on canine genetics projects and it's getting to be a very serious problem here also. A friend I have who is studying breed genetic evolution (and therefore has to get a picture of this exact question first), said they had a computer get fried when it tried to compute the inbreeding quotient on one breed they sampled (she wouldn't disclose what it was for privacy purposes and the fact that the study isn't done yet).
You don't have to breed mother/son etc to get high inbreeding quotients. It can happen when you start selecting out lines which don't go back to certain "typey" dogs, to fix characteristics. If you've got a six-gen pedigree and most of the males are the same name, then you've got a very inbred dog. If you've got an eight-gen pedigree and most of the males are the same name, you've still got a big problem genetically.
I know from studying show BC peds that this happens quite often - I get ill looking at these peds sometimes because I know there are genetic problems in these lines - and US breeders are taking THESE dogs as the models for the "new" AKC breed, rather than the healthy, genetically diverse working lines.
Now someone needs to do a highlight on GOOD breeding.
The problem is that until the kennel clubs change their basic philosophy that ideal looks equal the ideal dog, it will not be the "champion of the purebred dog" that will celebrate good breeders who value function (even suitability to be a companion) and health over what is winning in the breed ring.
For instance, the ridge on the Ridgeback is a spinal deformity. I didn't know that before. One in ten is born with a hole in their spine or base of the brain. The tail on the pug is also a deformity. Didn't know that either. Do you think breeders would agree to breed away from these dangerous traits? One of the points of the documentary was that instead of breeding away from these traits, breeders are culling dogs that don't have them!
I am in love with a breed that is distinguished by a lethal mutation, the Chinese crested. But, they don't require that every Crestie be hairless and even the hairless dogs can be shown shaved down. I think that's reasonable. The more hair a hairless dog is "allowed" to have, the better its health is - resulting in more normal dentition, skin, and ear/eye development. And puffs are just normal dogs though high maintenance in terms of grooming.
Surely RR breeders could allow unridged dogs to be shown - these are beautiful and amazing hounds and to me, don't require that ridge to be distinguished. I can pick one out from a frontal view and I'm not in any way a fancier. I thought the "old time" pug was adorable and surely those nice little dogs would benefit from being more than a lap ornament!
