Cool, you need to want to get him to chase. Reason being is it is scared of the gun, which has overlayed into the bird. We need to get conf. back into bird. So if you can get access to pigeons, take a pigeon, and extend wing out, pull couple hand fulls of feathers out of wing. You don't want this bird to fly well. Start at the body, work towards tip of wing. Do you know how to dizzy a bird? I want you to dizzy this bird then go to truck and get the dog.I would try and put this in light cover, i don't care if dog sees the bird laying there. work the pup into on down wind side, if it points great, if it don't great. Ok? Let the dog go in and bump, or you go in and flush. Let dog do what it wants. NO SHOT!! We are gonna get to that later. If the dog does not go after, its alright, walk off with dog, come back into bird from nother direction. Then see the response. It will take a few times of assoc this way to get it started on over the fear. Now i'm serious, if it goes and catches, let it catch!! Eat it if it wants, this will correct later. It has to regain dominance over bird. Iwont tell you what to do next because i want more workouts!! I'd say couple times a day a.m. then in p.m. This will work out. Wish we were closer and work together, i could explain what and why while we are working and you'd see it in the dog. Does this make sense?? Ask me ques??!! Gonna be cool, don't know how long but it sounds like boogers are not to bad!! Mean that!! Jonesy
