That is for sure true, there is a definite difference between the hunting bay and the alarm howl and the playing barking and the whining for treats and the moaning when you try to move them. I can tell which of my beagles it is for each one of these meanings. Mine have most definitely NOT had it bred out of them, but they are from champion hunting lines. The only thing I worry about when they hunt is if one of them will get lost, it's sooooo hard when you never find them again.
