This is an interesting question, and I have also wondered about it. But I do believe it's possible. My friend has a dog who is a mixed breed, some sort of husky mix- she looks like a mix of husky, greyhound, and gsd if I had to fathom a guess. I saw another dog that was absolutley idenctical to her, which is so strange considering her unique look. EVERYTHING looked the same on this dog, which was also a female. Everything from her build, to coloring, to markings- a very subtle white tip on her tail...to the way it curled and the size and set of her ears-which would be understandable with a purebred dog, but a mix? It was really interesting, and shocking to see!
