As the action continues, it's usually Gladys Knight being the most aggressive and noisy - she can sound like something with the devil inside. Tequila uses her wiley coyote ways to defend herself rather than speed, as she stands little chance outrunning Gladys Knight, who's probably the hardest sprinter I've seen. The whole game takes on a choreography of its own where deft maneuvering and footwork are the order of the day. Despite looking serious to the untrained eye, these pups are extremely good at avoiding injury or real confrontation. It's a ritual, a form of dance and instinctive socialization, much like seen in a wolfpack.
