Lets think about the dog for a little bit, what has been his reaction to birds, period?? How much bird action has it got to experience? What we might need to do here before problem gets worse is to allow more bird exposure, with no gunfire. We have to assume that nothing was done before. Think about the "bells ad whistles" going on in its head. MAYBE, never hunted before, or shot around, seen birds, new house, new mom and dad, new everything,you never know, and you don't always get the rest of the story from the humane society. I would much rather treat it like its a puppy, better to be safe than sorry. Dog Training 101: it is always easier to advance a dogwhen time is right, than when it is wrong. Patience is a virtue. What we need to discuss is what and how you have been doing the stuff to make a nice dog. Thanks Jonesy
