Huh interesting, I didn't realise dogs were a sub-species of wolf. Oh well there are many many other species out there that can interbreed but don't.
Like polar bears and grizzly bears as an example.
Basically the definition between species is ridiculously blurred because it doesn't actually suit the nature of evolution - that there is never a clear dividing line between one species and another.
