Were that my dog I'd find another decoy and training club. He looks like a young well balanced pup responding very well in "prey" drive and you want to get him to somebody who knows what they are doing and can work the dog properly.
In other words, nice dog, not good decoy. Go on the LEERBURG web site and watch some of the Michael Ellis videos clips. A trainer like Michael or one who has worked with him is who I would look for.
