Terms Used In Protection Dog Training By 1998 Prey Drive Prey drive is the desire to pursue, bite and vanquish. Prey drive is stimulated or trigger by movement. I have an extensive article on my web site titled Understanding the Drives of Protection Training that should also be read by people interested in this work.
