This is one reason why I favor large Labradors. Most trouble never gets started due to size. I don't care for the aggravation either, and like others, I don't want my dog abused by other's dogs.
Reminds me of a dog owned by a friend, "Ace". Ace caused a lot of trouble with smaller dogs on our hunts and was a real pain in the ass. His owner didn't do alot to stop him and we didn't hunt with him alot as a result. Ace didn't generally cause trouble with my dog, who outweighed him by 20 pounds or so. But one day as we were unloading and getting ready to start, Ace thought he'd take a poke at my dog, and before long my dog had Ace by the upper lip and was dragging him around the pickup with all kinds of whining and crying going on. By both dog and his owner.
"Aren't you going to stop him?"
"Uh, no, I don't believe I will."
