If you're doing a lot of hunting for fur and the dog is retrieving, take a look a the Deutch Drathaar. You'll want a dog that can defend itself and dispatch wounded critters then bring it back to you like it's the king of the world. That would be a DD.
those are one of the few i have heard of but i have a hard time beliving some of the stuff you hear. whice i run hounds most of the time i just named beaver and muskrat becuse i heard a guy talking about a game call that would work on beaver and muskrats. it was easier to bag a few for the table then trapping. so mostly looking for something that can take cold water and fish game out after the kill shot
