Is that possible? A customer came in today with a big black and white fluffy dog that I thought was some kind of Berner mix or something. When I asked what he was she said he was a pure bred Border Collie! I didn't press the issue any further, so I don't know if he was a rescue that she was claiming was purebred or if she actually got him from a breeder. I snapped a quick picture, but it doesn't do him justice. He was really big and stocky. He was bigger than my coworker's lab. Thoughts?
