uhhh Happys is mixed black and pink all over, including her mouth, skin and pads and nails, and she is a purbred border collie, I know her pedigree a long way back. and I personally know both her parents and several of her siblings and half siblingsTo figure out if the dog is purebreed or not look at the roof of the dog's mouth or tongue. If it is solid pink then it is purebreed. IF there are black or patches of discoloration then it most likely is a mix.
