He just has "loose elbows", it may just be because of how his brisket is constructed though. No biggie.
I really don't think he's a Silky. Nor do I think he has any Silky closely in him either. He looks to me to just be what some might refer to as a "throw back". No, not throw away....a throw back in the lineage of type. Basically he looks like a Yorkie of old. Has anyone ever asked you if he's got Schnauzer crossed in w/ him? lol, someone over my shoulder just asked that and I answered quickly that he's a Yorkie.
The list, while technical is somewhat long. His muzzle has too much substance for a Silky's type....you know what, I really need to be able to point it out to you and I just can't. I'll go grab some pics if I can and come back here. Gimme a sec...........
