This is kind of a stupid question. I should be able to think of something myself. I recently taught Fraser to roll over. He wasn't mad about being on his back so it took a while, but he does it readily now. However, there is interference with a command he already knew which is twirl for which I make a little stir in the air. When I want him to roll over I tell him to lie down and then make a gesture in the air that is clearly too close to the stir gesture as poor dog gets up, twirls, lies down, acts confused. So, that's one part. Need a gesture for roll over that doesn't look like the twirl one. Also, when I ask him to lie down, he now associates that with roll over. A clear roll over gesture would help him differentiate between an ordinary lie down gesture, flat hand, palm down and roll over. I'm sure I'm making this all too complicated, but it's got me stumped.
