Using Threshold Training to Interrupt Fixation and Regain Attention
🔹 Threshold training works by exposing the dog to the trigger at a level that is challenging but still controllable.
🔹 Yellow Zone = Tommy notices the mail slot but can still think, respond, disengage, and recover.
🔹 Orange Zone = fixation and drive begin increasing rapidly. Response time drops and attention narrows.
🔹 Red Zone = Tommy commits to the attack behavior and stops responding.
🔹 In this session I’m using the “leave it” command, movement, distance management, and low-level ecollar stimulation as Tommy begins crossing from yellow into orange.
🔹 The goal is not to avoid the trigger completely. The goal is to challenge the dog without losing control while gradually reducing the gap between the workable zone and the trigger.
🔹 We only started indoor ecollar work after first teaching the food game and “leave it” outdoors where the environment was less triggering.
