I bet Jimmy almost exploded. He is coming along well if you are doing that sucessfully. When I start training again we need to get together.Live shackled bird, popper gun, handler, dog, "judge" behind dog with a heeling stick. If dog flinches, handler says "Sit" and "judge" uses heeling stick. Once he sits for 2-3 seconds, release him to get the bird. Lather, rinse, repeat as necessary until steady and then go to maintenance.
