I've been teaching Zac sidestep. There are still a lot of positional variations I want to work on with him but I think he's looking quite good with it... some times . He's a bit slow to start with in the video because he thought we were playing a different game. I mix training "Front" with sidestep as we worked on both at the same time and "Front" was foundational to Zac gaining confidence side stepping with his hind legs and understanding that hind leg position matters. For teaching him to walk sideways in facing me in front I simply told him "front" and then moved to one side and told him "front" again, it didn't take long for him to make the connection. To teach him to move sideways beside me I encouraged him to lean against me and then stepped away from him so that he moved sideways to continue leaning. Currently we need to work more on the cues for him standing across in front of me and him stepping away from me to the right. Yes, I know... Gus makes a better door than a window! But he was very good about not standing in the way most of the time.
