Why not open mouthed?

I like a dog to be closed mouth unless it is looking at a hog. Then I know that there is a hog to be caught. A dog that is open on the track barks when it smells a hog. Maybe the hog is there and maybe it isn't. In my oppinion, most dogs that are open are colder nosed dogs and they could be barking at a hog that is long gone. I could be wrong, that is just my oppinion. Our curs will only find a hot track and will not open up unless they are looking at the hog. Its just the way that we hunt. There are many different hunting styles. One isn't better that the other, you just have to find one that suits you.
