I could, but have other things I need to focus on right now, get into all this but suffice to say
1. The Kennel Club is only an official registry much as it should be possible for them to be more active in protecting breeds. However, they have put a number of dogs with perceived problems, on an 'at risk' list which means the dogs in those breeds who takes BOB at Champ.shows (not sure about Open and lower shows?) are required to be examined by a vet before being allowed to go forward to the Group. Quite what happens in too many cases re the 'vet inspection' is anybody's guess. That GSD was allowed forward.
2. There is a Breed Standard for all recognised breeds, drawn up originally by those involved in the various breeds, and then submitted to the KC to be ratified. Breeders should be breeding to these Standards and judges should be judging to them, each dog against the BS and then each other in the ring. BUT judging is subjective and certain aspects of a breed mean more to some judges than others. I'm a 'head and front' judge (or was, I'm retired now) and would heavily penalise an entry who didn't come up to my interpretation of the breed in these areas.
3. Breeders are not all producing cripples. Far from it and good breeders would be horrified if the unexpected happened. However, we are dealing with living beings, and despite every effort to produce 'the best', things can come out of the woodwork (recessives!!!). This is especially so when two lines that have never been put together before are, and produce the unexpected. Which is why outcross mating is such a lottery - it can produce the best, but also the worst! For this reason line breeding is 'safer'. Further, environment and rearing after the puppy leaves a breeder has to be taken into account, when things go wrong. And for sure, cancer hits dogs just as frequently as it does humans, sadly.
4. I'm afraid I don't hold the ABS in high regard. I suppose it helps to raise the goalpost to some extent but the cynic in me suggests you pay the fee and that's about it. And I've heard first-hand, a breeder we visited to look at a puppy (and ran!) telling somebody on the phone that they were on this Scheme when I knew they were not!!
Buying a puppy is still, and probably always will be, a buyer beware situation. However, I would expect a reputable breeder to be worried about every puppy they sell, and be there for them throughout their life. And take note of any 'trend' that appears in their breeding programme.
