Just wanted to mention also, watch your dog during deer season. My dog is also very afraid of gunshot, fireworks and thunder storms. If I am home she stays near me, and she is ok ~ just anxious. If I am not home, and she is outside alone, for some reason she runs off (she NEVER does this unless there is gunshot, thunderstorms or fireworks). Actually, I have talked to several owners whose dogs react this way. Anyhow, if your dog were to react by running off during deer season, there is a very good chance that it will get shot. Hunters understandably hate to see running dogs in the woods, too often they are up to no good. I would hate for your dog to get shot because someone assumes she is out chasing deer on their property. And yes, there are meds out there that are low dose and calming. My sister uses them for her dog. The collar thing might work better, as it would be a shame to have to have your dog doped up the entire rifle season! Good luck on getting it to go away though. Seems like once they develop that fear, its there to stay.
