So many of the books and articles I have read about treating fear-based aggression tell me to start with teaching a solid Sit, Watch and Stay. The Stay I have had some success with, but the Sit and Watch are iffy. He is getting much better at sitting and waiting before I open the door to go out, but how do I go about getting that quick response every time. It seems when I am training, specifically for Sit and Watch, he will do it pretty well because we are doing it over and over and he is not really thinking about something other than what he needs to do to get the treat. My thinking is that I need to mix in other cues so he has to pay attention to what I asked for every time in order to get the reward, but when I do this, he seems to get tired or bored or something else, and shuts down. By this I mean he will lay down on the floor or walk away or start scratching instead of doing what I cued. Sometimes he will just sit there looking at me, waiting me out. I should really start timing him, because it seems like 30 seconds or more have gone by since I gave a verbal cue, then he will finally think, "okay, I'll roll over". Any suggestions?
