This is partially true. If you are speaking of bird dogs you are way off base. If you are talking about hounds you are right on target. Hunting hounds are not tolerent of small children or other animals. They are bread and trained to not be nice or they would not be good at their job. We hunt with an uncles Blue Tick hounds for coyotes and bobcats and I would not want them in the house around my kids.
Hunting dogs do not stay in the house around your children. True hunting dogs are kept in a pen and not really socialized beyond being able to catch the dog. A socialized dog will stay under your feet. You want the dog to get away from you to find game. The only social training I give a hunting dog is I blow my truck horn when I feed the dogs. That way if the dog is lost it will hear my truck horn and come to the truck. Yes, we use GPS collars and all the technology we can but nothing is perfect. We still lose dogs for a short period of time.
