I have a silly question. Do you have any special markers or do you teach a whole different command for when you want a trick performed in front of you, or on your side? I mean, like in a heel position (on your side) or facing you (in front of you). I've always taught my dog to do his tricks in front of me, since before I knew anything about training, because I like having eye contact with my dog when performing tricks. So now even if he is on my left side, he will position himself in front of me, and then do the trick. So far I haven't required my dog to do any trick on my side, but now that I want him to learn some serious heelwork, I'm wondering about the "correct" (official, orthodox? ) way to have him do tricks like down and sit on my left side.
