Here is my dog Rocky, taken last summer shortly after we got him. My step dad took him from a construction site in Philly. He was tied to a rock (hence the name) and was underfed and had construction tape/tar matted in his fur. He's part border collie, shephard, chow chow, and prob some more...
(and a recent pic)
Before him, I had a half alaskan malamute/half wolf (her mother was a wolf)...beautiful dog, but I was a baby and she was wild (always knocking me over) so we had to give her away to someone with a farm. I also had a half german shephard/half terrier from 2nd grade until this December when we had to put her to sleep.
