How to "soften" a dogs mouth ??

[Jordan]

To clarify more, Drake is 3 years old. My dog knows the normal things that I've taught him from watching DVD's and reading books. Sit. No. Lay. He's not advanced to know heel, back, hold, left, right, etc. I dont have $5K to spend to get this dog right which makes me believe I'll just deal with him biting the ducks rather than carrying them back to me. Just figured there was a cheap/easier way to break this habit.

If I shoot multiple ducks, he will get the first one that he sees. Bring it back to me (while chomping it to get a better grip is guess). He will then sit, I will line his face up with my hand and call his name (Drake). He goes and retrieves the other duck and chomps it on the way back. Same with the 3rd duck, etc.
