I'm still having trouble with this. Clicker is not an option because I've been using it as a distraction to get him to stop licking his feet. I'm also going to put him back on a small dosage of anti anxiety meds. Everytime I give him a non chewable item, he wants to chew it. I've tried telling him to stay. I think I'll start saying "hold it" because when I want him to drop his tennis ball, I say "drop it". Any suggestions?
