Hey sdm I gotta guy who has some of the best duck dogs out there. These dogs not only retrieve but can also call the ducks as well. They can do a great hail call and their feeding chatter is better than the competition callers. They do slobber a bit on the call so in extremely cold weather it's best to have a few extra calls handy since a few may freeze up on them. I'll see if he's got any left. I can get you a discount. Ballpark eh around $750,000
Oh and they can also be used as a trolling motor, doing the doggy paddle.
