Speaking of "Heelers"...
It's one breed that I've never owned, but there was a guy who lived up around the corner from the house I grew up in, that had an incredible Heeler.

That guy rode his motorcycle everywhere he went, and that Heeler rode with him on the back seat! No box, or straps or anything! He just stood there and balanced!
Obviously, not the smartest thing in the world to do, but it was pretty amazing to see as a kid!
