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. I recommend you study my training video titled The First Steps of Bite Training. Play Drive Play and prey drive are very close to the same thing. The fact is that a dog can have a nice temperament and have play drive but little prey drive. This can be seen in dogs that are very willing to play with their handler but don't really have a lot of drive to chase or make prey by playing tug.
