Dogs, like wolves, do not survive on their own. They rely on each other to survive. It is part of the group dynamic to hunt together, raise puppies together, live socially together. There is, of course, a hierarchy within the pack and unless you, as the human leader establish dominance over your dog, your dog will assume that role. Pack drive is elicited by petting, praising, smiling, grooming, playing, and working with your dog.
Prey Drive is associated with hunting, chasing, and killing prey for food.
You never see a dog chasing a parked car. Prey drive is activated by seeing, smelling, and hearing. The dog will listen, smell the air, stalk or track the victim, chase it down, pounce, bark, shake it, and tear it apart even if it is just an old stuffed teddy bear. Destructive behaviors such as tearing, ripping apart, carrying, eating, digging, and burying are associated with prey drive. Prey drive can be stimulated by the use of hand or object movements, a high pitched tone of voice, throwing a stick or ball, chasing or being chased, or tug of war games.
