The Look At That protocol, commonly called LAT, is one of the most effective and humane techniques used to help dogs struggling with reactivity.
For many guardians, living with a reactive dog can feel exhausting. Walks become stressful, everyday outings feel unpredictable, and simple situations like seeing another dog or person can quickly escalate into barking, lunging, or pulling on the leash.
Reactive behaviour is often misunderstood as disobedience or stubbornness, but in many cases, it is rooted in fear, anxiety, frustration, or overstimulation. Dogs react because they are emotionally overwhelmed, not because they are trying to be difficult.
The goal of LAT is not to punish or suppress those reactions. Instead, it helps dogs change how they feel about the things triggering them.
The concept behind LAT is surprisingly simple. When the dog notices a trigger — such as another dog, a stranger, or a bicycle the handler marks the moment the dog looks at it using a marker word like “Yes,” then immediately rewards the dog with a high-value treat. Instead of trying to distract the dog before they see the trigger, they are rewarded after they see it.
Over time, the dog begins associating the appearance of the trigger with something positive instead of something stressful. Rather than reacting emotionally, the dog starts calmly observing the environment and looking back to the handler for guidance and reinforcement.
One of the most important parts of LAT training is distance. Dogs must remain under threshold for learning to happen effectively. This means the dog can notice the trigger without barking, lunging or becoming overly fixated. If the dog is too close to the trigger and already reacting, the brain shifts into survival mode, making it difficult for the dog to process information or learn new behaviour.
Because of this, training begins farther away from triggers than what many people expect. A reactive dog may initially need to work from across a parking lot or quiet street. As the dog becomes more comfortable and successful, the distance can gradually decrease over time.
Another important part of successful LAT training is repetition through intentional practice rather than waiting for difficult moments to happen naturally. Many guardians make the mistake of only trying to work on reactivity during stressful walks or unexpected encounters. The problem is that real-life situations are often too intense and unpredictable for learning to occur effectively.
Instead, dogs learn best through controlled, repeated exposure where the environment can be managed and success is possible. Repetition helps build familiarity, confidence, and emotional stability. The more a dog practices calmly observing triggers and being rewarded for it, the more automatic that calm response becomes in everyday life.
With patience and structured repetition, the Look At That protocol helps dogs feel safer, calmer, and more confident navigating the world around them.
