how do you really tell the diff between the silky's and yorkies? my belief is that in my job as a groomer, that a certain breed comes in as X breed, but may not be that breed ,even if it is papered. So many come from puppy mills etc and even the breeder can't tell you what is up. So what is the deciphering difference between a yorkie and a silky?
Or is the Aussie influenced by the Silky & Yorkie? To my understanding, without nosing around the internet as it is late, the Aussie was the last of the three to get AKC registration, if that means anything. Colors other than the traditional black & tan are also acceptable with Aussies.
I have a couple of Aussie terriers now, and had a Yorkie long ago. There is a major difference, not only in size, but in the bone structure, most noticeably in the jaws as well as chest and front legs.
The last time I actually got up close & personal with an adult Silky was over 20 years ago, when I had the Yorkie. If I recall it was mainly a size difference, the Silky seemed like an oversize Yorkie, I imagine a runt Silky & a Yorkie at the top end of the breed standard would be almost the same, perhaps there are a few differences an experienced breeder would be able to see & feel, that person is not me, as I don't breed.
