Our dog is a lab-pit-pointer mix, as far as I can tell. Or maybe she's a short-haired cattle dog. I wish I had a dollar for every time someone tried to guess her 'breed' and I had tell them I had no idea, she's 100% mutt.

But I would draw a distinction between dogs bred for a practical purpose (border collies, labrador retrievers, blue tick hounds, etc.) and 'dogs' bred purely for grotesque effect (I won't name any because I would feel bad about disparaging a dog for human sins, but I'm sure we could all think of a few).
