Not the local pet shops. They don't sell mixed breeds (but DESIGNER mixed breeds, or other mutts with fancy names are welcome.) but still, I've never seen a greyhound in there, let alone a greyhound X whippet, which would be a rather unlikey thing for them to stock. If you just mean "animal" that can't be found, than of course, they do have dogs. lol, I'm not being much help, am I?
