I hear more complaints about breeding munchkin cats, http://en.wikipedia.org/wiki/Munchkin_cat and that people shouldn’t breed cats with short legs. However, I don’t hear complaints about breeding daschunds, even though they get back problems due to short legs. Is there a good reason why?
I don’t think there would be any worries about breeding München cats. I’ve been to München, and it’s a very nice city. People seem healthy there, so I don’t see why cats should have health problems.
What?
Munchkin cats?
Not München?
Never mind!
Ain’t a Munchkin a small donut? You’re suppose to raise these cats to eat? 
I’m guessing that this is because the dachshund as a breed was ‘developed’ for a purpose, hunting bagders IIRC, which meant they were required to be shaped so that they could go underground. The back problems, and similar problems in other breeds, have become apparent in more recent times with breeders trying to produce dogs as close to the Kennel Club pedigree description as possible regardless of any ‘side effects’ such breeding to type leads to. And yes, there is plenty of disapproval out there for people who breed dogs with a predisposition for painful health problems, hip dysplasia in German Shepherds being a well known example. You could say we are learning from our mistakes and realise that breeding cats to perpetuate a genetic abnormality when it ‘helps’ neither man nor beast seems overly indulgent and wrong.
