There are some threads, but really this needs to be done. Compare and contrast please. Are the breeds more like Labs and Goldens where they're pretty interchangable as far as different breeds go, or more like Goldens and Chessies where they are very different? Why so many variations for what seems like a rather uncommon sport (at least now it seems bird hunting is more common than hound running by 100-1). Say that I lived somewhere with raccoons, where do you even start picking which breed to run?
