Gus's head tends to follow his paw and the water everywhere sounds familiar! From the expression on his face the water everywhere might be even more important than getting the floater...Jinx sort of does this!! Though instead of using her paw to fix it out, she just kinda dunks her whole head in and tries to bit it and pull it out. Often times she only has success in dumping water every where.
In theory that works great. Real life, not so much. So, Tigerlily and I came up with a plan. We based it off of BAT but instead of you get close to decoy and you retreating . Our version was decoy approaches, Cue the dog to get behind "Please leave", person leaves. This was to teach the dog if you are uncomfortable go behind me and I'll make them leave.
I should have known you and Tigerlily would have thought about this before . I totally love the idea of your training game/exercise. There are just so many good things this could teach an aggressive, shy or territorial dog. It teaches the dog a signal to clearly communicate fear in an acceptable way, it builds up trust, it reduces fear because it shows the dog that approach does not mean contact, it rewards for nice behaviour by the stimulus going away...
