Try Chesapeake Bay Retriever. I have seen them in field trials and duck hunting. They are not cheap. No good hunting dog is. It is in the breeding, unless you are very lucky.
Also I think you can get duck at the grocery.

^^And he has made several threads asking pretty much the same questions. IMO the OP does not have much experience with dogs, (in another thread he asks if Labs shed). Training a hunting dog is not easy and if someone has no experience they should seek out and heed the advice of a good trainer, otherwise the OP is just setting himself for disappointment. I am all for hunting dogs and have hunted with them in the past (black and tans, labs and pointers). However those were all dogs that were owned and trained by friends. I have owned dogs all my life, from Labs to Danes to St. Bernard's and all sorts of mixed breeds. They have all been family pets, I am not sure I could do the work involved in training a dog to hunt. It really is a huge commitment.
