As long as a mutt from the pound can smell trace amounts of cocaine on $100 bills and a cockerspaniel can sniff out cancer cells in a human body, then I'll continue to say, no matter what kind of dog your running, Nose isn't the problem, what's in the brain to do with the scent is. You don't have to add hound, just find what you like and cull thru them ruthlessly.
x2...it is not the nose it is the brain...you need a dog that won't give up the track...
