That would be doubtful since the dog has never had any interaction with a bird according to the OP before he took it dove hunting. It sounds like the dog is fearful and has gone to the owner for comfort because it does not have a good understanding of what is happening and does not associate the noise with pleasure. To me it is a clear sign to stop shooting over the dog and get it properly introduced to the gun before the damage in not repairable. It would be nice if people ask how to introduce a dog to the gun or where to look for help before they screw the dog up.
