I also state give for a release. If he doesn't release I pat him on the head and say good dog. Then I take a front paw and slowly apply a small amount of pressure and say give me. I will apply slowly more pressure until he has given me the training dummy. Once this is done I let go and pat the dog for doing what I want. That way I see no need to carry a pocket full of treats when out hunting with him. He will be expecting treats each time he does good when really only a good pat on the head will work fine. They just want to know they are doing what you want them to do. Once they understand they will not hang around for another treat, but will start hunting again for another bird.
