Duck hunting

This is good, according to reliable sources.  I don't hunt much anymore or train retrievers for that matter any longer but I think you may be pushing the time line for this upcoming duck season.   The biggest mistake people make with retrievers is taking them hunting before they have the yard work done.  Bad habits formed while hunting are very hard to cure.  Breaking is the number one problem I see from dogs that are taken hunting before they are steady to wing and shot.  If you decide to take your chances, don't forget to introduce her to the decoys and teach her not to retrieve them. :)    Also, be prepared for major panic if she gets tangled in the decoys and starts dragging the whole raft after herself.  Been there, done that. lol

There are several commands that are key in hunting.  Sit, for the obvious reason.  If the dog isn't sitting, he won't see where the bird falls.  Hold, because if the dog won't hold the bird till he gets back to you, lost bird.  Here, for the obvious reason.  Drop, also obvious.  All of these have to be trained separately and then combined with the added distraction of birds.  Remember that many times ducks are wounded and not killed and they dive under water when the dog tries to pick them up.  If you don't have a very good recall, this can become frustrating as your dog swims around in frustration trying to catch the duck.  In the meantime, you the hunter, are watching ducks flare away from you because of the crazy dog in the water.  If your dog barks when excited, this can prove problematic.  There is a lot to hunting with a dog and the training is necessary if you want a pleasant hunting companion.  Below is another site you may want to look at for ideas and reference books.

EDITED to add the most important thing. DUH!  She has to be introduced to the gun and the shot BEFORE she goes hunting.  The boom from a 12 gauge shotgun is loud and you don't want her first experience to be her first duck hunting trip.  Trust me on this one.  More dogs become gun shy from their first hunting trip than you can imagine because they weren't properly introduced to the gun.   This is very hard to fix once it happens, very hard.
