Actually, there is no best all around dog. There are so many types of game that nobody can be an expert in all of them. How many expert hog hunters are expert ptarmigan hunters? Since we can't be an expert in every type of hunting, how can we judge whether one breed is better in some field we don't have much experience in?

Take any dog out of its element and it will have to learn the terrain and game all over again. Ex, chukar hunting in WA is much different than grouse hunting in PA which is different from the cornfields of IA. The local dog which knows where the local game lives and how to handle them will win over the dog that doesn't.
