All she can do is, sit, lay down, shake paw, paws on chest and speak. She loves rolling in snow and on the carpet, but, I don't know that I could teach her to complete a full roll over. Of course, liver treats speak volumes. Who knows. We use the stay command when we play "Find Mommy." I put her in stay and hide...simple enough, and then I call for her to find me. She loves it, but mostly she loves the treats.
It's all pretty tame compared to what you get Hector to do. But you are a great teacher, and you have so much patience, and, of course, Hector is an apt pupil.
