Dave, you will want to get your dog used to the sound of a shotgun going off. Excellent, basic obedience is a must afield.
My Chesapeake was gun shy as a pup but I had an older Lab that helped to steady him. It didn't take long for the Chessie to associate the noise with fun.

I never got heavy into training like the ol' man did with his pigeons and field trials.

Nothin' like a crisp October morning chasin' wild chickens on the Eastside.

Edit:
Don't take Dick Cheney.
