Wow what a great, instructive video Jess! I'm so glad you posted it - I will try working Pippi into this approach. Big challenge with her is that she never likes to be on her back for any length of time - I think something may have happened to her involving her belly prior to being rescued. It took forever for me to get her to let me touch her belly - she does now, but she's the only dog I've ever known that does not like belly rubs, and any attempts at getting her on her back are impossible unless you hold her in position on her back, but I can't Dremel her and hold her in place at the same time. Definitely this is worth working on to get to where you're at with your dogs. Thank you so much for posting that video!
