haha that was a hard one, but I ended up teaching Mel dead dog instead, I find it adorable when I introduce him to people. I ask their names and if its Sally (or whatever the name I insert) I tell him "hey Mel would you rather be a dead dog or Sally?" and he slowly becomes a dead dog, lol. sometimes he would accidentally roll over. Now he has them down pat and can do them both. Just keep trying, it will click one day!
