I trained backing up exactly as in the video. I had something blocking one side and my body blocking the other side so she had no choice but move backward in a straight line. The only other thing I could suggest, depending on what Yogi is like. I also used to loop a leash around her stomach and held both ends of the leash. She had a tendency to want to sit, rather than move backward, but having a leash around her, I was able to control her almost like a puppet. When she want to sit, I held her up. I'll try to get a pic/video of what I mean. She also learned that she only has to back up 3 steps and her 3rd step would be really half assed, so now we're working on 4 steps, so that she does 3 good steps backward lolSent from my iPhone using Tapatalk
