Thanks for the info about the ASCA. But why is this any different than miniaturizing any other breed such as the bulldog, shar-pei, etc? Is it any worse?
It's not different than miniaturizing any other breed. However, in my opinion, miniaturizing any breed over a short period of time is a bad idea, because it involves changing the gene pool significantly in a few generations. In the case of the 7 lb. Aussie that is an 80% loss in body weight if I did the math correctly. That would be like having humans that are 25. lbs. as adults in just 3-4 generations!
You can imagine then, the number of other genes/traits that would be affected by such a drastic change in the gene pool. At the very least, you would have a different breed, but IMHO you'd have a bunch of really genetically messed up dogs.
And, that is assuming that only Aussies were used to create the "mini". (In many cases dogs are out-crossed to small/toy breeds to reduce the size in one generation, which is a mixed breed dog, not a mini Aussie.)
Someone with a better background in genetics could probably explain this a lot better, but I hope that info is useful!
