My dog was never gun shy until she was about 6. I was working in Montana, had her with me and she would spend the day flushing birds while we worked on a drill rig. One afternoon a fast moving thunder storm came up over the hill, and as we were trying to get the equipment shut down to wait out the storm a lightning strike landed nearby. My dog and my coworkers came screaming back to the trucks and jumped in. Pretty sure the dogs got a buzz from the lightning strike because ever since my dog hates any loud booms. Shes 10 now and we went on a pheasant hunt with a buddy haven't had time the last few years, or maybe I was just avoiding it. She still knows its hunting and loves it, but she is shaking and upset unless directly on or after a bird. Breaks my heart to see the ol girl so scared, shes my best friend, and I think its pretty late in the game to get her right again. She bad wants to be hunting, but maybe its time to give it up. Any thoughts on a dog this old?
