I play tug with Jackie, but I initiate it. I will hold out the rope and say "Take It", and a tug ensues. I let it go on for a minute or two, then I say "Drop It", and I make her do a sit or a down for a minute or so to calm down, and we start over again at "Take It". Thsi way, no one gets too revved up, and we can both remember who calls the shots.
I agree about the choke chain. Sure, it SHOULD be obvious that you need to ask someone how to use it correctly. But we are talking about HUMAN BEINGS here. It's not completely out of line to share what should be obvious . . . because I bet that there's at least one person who would read it and say "Really? I didn't know that!" And if we can help even one corgi owner (and by association, one corgi) then it's worth it.
