Thanks for bring yet another of the unscrupulous Breeders to our/my attention.
It's a real shame that there are SO many out there, that downsize breed with the preponderance of medical issues, which are common to that practice.
In my opinion, I think that the Yorkshire Breed is generally getting bigger/heavier as the years/generations pass.
I can see this putting a lot of burden on our good/responsible Breeders, trying to accommodate the AKC weight restrictions. The (within specifications) well proportioned and healthy Dogs that are available, will not live forever. The AKC needs to "rethink" it's standards. IF this were to occur, I think it would considerably reduce the interest that some have, for the diminutive.
