I am going to sit on the fence a little (can't help it, I am a Libra
)
With regards to Seaanglers post, I think it is unfair to tar all breeders with the same brush..in fact, I would go further and say that the vast majority of breeders (certainly that you would find at Crufts anyway) have the best interests of the breed at heart and would be horrified if they thought anything they were doing was detrimental at all. However, e.g in a numerically large breed such as CKCS, which is also popular with puppy farms, all you need are a small % of irresponsible breeders (be they show kennels, hobby kennels, BYB, PF, pet breeders, whatever) to breed without care and you automatically can have a large number of genetically damaged puppies into the gene pool. Also, with regards to 'designer dog' breeding I would suggest that the vast vast majority of these aren't bred by those who would not be exhibiting pure breds at crufts!!!!!
I think * what I am trying to say is that you can't just tar everyone with the same brush. There are, as we all know, different types of breeders. i suppose the easiest way to differentiate would be responsible v. irresponsible. And yes, I do accept that you will get some irresponsible breeders amongst the showing fraternity and also some extremely responsible pet breeders.
Ooops, don't think I am putting this well at all, hope it makes sense - I'll stop no before I wind myself in more circles
