Bird hunting and shooting deer while dog is present

Yes, deer hunters can have their dog with them.  However, it is unlawful to hunt big game with dogs except black bears and mountain lions in certain units and with a valid hound hunter permit.  Idaho's definition of hunting is broad.  It is easier to comply with the law if you don't have a 'hunting' dog with you while pursuing deer.  If the deer is observed because of the actions of your spaniel, taking the deer would be unlawful. "Hunting" means chasing, driving, flushing, attracting, pursuing, worrying, following after or on the trail of, shooting at, stalking, or lying in wait for, any wildlife whether or not such wildlife is then or subsequently captured, killed, taken, or wounded. Such term does not include stalking, attracting, searching for, or lying in wait for, any wildlife by an unarmed person solely for the purpose of watching wildlife or taking pictures thereof.
