The "Mini" aussie was actually the original size working dog...if you look at the history of the breed standard, people have been breeding them BIGGER over the last few decades. So I think it would be more accurate to say that what we call "standard" aussies are actually "super-size".

I've never heard of a mini heeler and a quick search didn't turn up anything. It's possible, or he may be a mutt who looks like a little heeler.
