I've hunted with a few Chessies and much of what has been said can be true. It can also be untrue depending on the dog. Like labs, some lines of Chessies have more mental and/or physical stamina than others. These can make for good upland dogs especially if conditioned properly.
Like any dog breed, one needs to do their homework and check out the lines of whatever breeder is being looked at. Every breed has lines that are not the best for a particular area of hunting but may be unsuited for hunting in general. It is no different than winnowing out potential health problems in that you need to know what questions to ask, what information to look at, what it means, and read the responses for further clues. It requires detective work along with an occasional gut response to ferret out the truth. And you may still be wrong either way.
