Debbie - my brother has a purebred blue tick (one eyed Bart) and his son who is half BT and half Beagle. They both will kill anything that comes into the yard non canine. The list includes ducks, squirrels, birds, and skunks (and probably more my brother hasn't shared). They will shake the poor little creatures to death. They go insane when they see the neighbor's cat. I have no idea if this is a common trait or just lack of proper training but it scares me.
