I saw your posts when I came across this website via searching for punishments that my master could try out with me... I joined just to tell you that I wish my master was as cruel as you with his punishments and orders. He is too softhearted. I'm sure he could take a lesson from you.

And, at minimum, I consider public anytime I have a more than likely chance to be caught, like in my backyard or at a park
