This is actually something being debated in Australia. Until a few years ago, Dingoes were considered the same species as the regular dog Canis familiaris. Recent DNA studies have shown them to be distinct, however. So now there's Canis dingo. Only, Dingoes can interbreed with the regular dog, which normally is the test for them being the same species. Maybe that makes them a subspecies?
So, yeah - even we don't know what they are. If they were raised by humans, they are happy friendly doggos. If in the wild, then they're dingoes.
