I've never felt co-ordinated enough to try clicker training; it's one more thing to do, when all I want is focus and obedience. My dogs listen to my voice or watch the hand signals, no gadget involved. Just me! Hope your surgery goes well; if the surgeon wants anesthesia, there's a good reason. Asleep during surgery is a GOOD THING; screaming, snarling, and flailing will definitely annoy the nice doctor and make things go less well. Opa, all the best. Mary
