I have 5 Blue Heelers, they are all working dogs, and frequently go out with my sons when mustering and the like. The oldest male dog, Dylan, has been kicked on numerous occasions, but always gets back up and back into the job.
As territorial dogs, they are incredible dogs. Many times I have been in Halls Creek, have left my keys in the car, unlocked, and for some reason it has never been pinched. The dogs have never been tied in the back of the tray either, good security.
