One of my younger brothers had a dog that was part Aussie cattle dog and something else. It used to herd his wife around the house. His previous house backed up to some apartment buildings. A bunch of guys would hang out at the wall behind his property and drink next to the dumpsters.

A guy climbed over the wall to take a dump in the vegetable garden, and my brother sent the dog out.

Nobody got hurt, but nobody climbed over the wall to relieve themselves again, either.
