You want to fix this dog - You need professional help. Contact Krytal Creek Kennels - google the name. They are located in Cedar Grove.

Beating a spoon on a pot or pan or taking a dog to a trap range is all wrong. The dog needs to associate the bang of the gun with game ie. birds and be happy as the retrieve is the reward the dog recieves at the end. Someone did something to turn this dog off.
It can be done but is better done by people who specialize in fixing man made errors!
