I'm sure there could be other hypothetical occasions where the dog collar might be of use -- for instance, if some dude wanted to pin one of those white ribbons on you.

So if, in the theatre of your mind, you were to meet the guy with the white ribbon, it is conceivable that you would put on a benevolent, pacifistic face like unto the Quaker man of oatmeal fame, and say unto him: "here, a biscuit for thee, my friend."
In my mind's eye, I can see the ribbon dude romping happily on his way, wagging his happy little tail too, if he had one.! :)
