Host Elise Hugh introduces a TED Talk by dog agility competitor Jennifer Crank, who demonstrates an agility course with her border collie High Five and explains how the sport depends on precise interspecies communication. Crank describes the structure and difficulty of modern dog agility, the six primary cues handlers use, and why dogs respond most naturally to motion and body position rather than voice commands. She then connects these lessons to human relationships, emphasizing clarity, timing, consistency, and trust in any form of communication or leadership.
