I would say Labs....we have LOTS of hunters here....people are ALWAYS breeding labs...it's very sad.

When I've been to the shelter there's lots of labs, gsd, and pit mixes.

There's an awful lot of poodles, shih tzus, and schnauzers that come in to be groomed but that's probably just because they need grooming more often.

I know the lady who runs Australian Shepard Rescue so I see lots of Aussie and border mixes around here also.
