The DDs I have been around have been great field dogs, not so much house dogs.
That, of course, has alot to do with the handler.

You teach a pointing dog manners. Then expose them to game.
If you are looking for a waterfowl dog that points, then the DD is at the top of the list along with the Griffon.
The best DD will never keep up with a Chessie or good lab in the water.
Or a Pointer or GSP in open country.
