‘Dog Whisperer’ Cesar Millan brings artificial intelligence to pet training demonstrated an AI-powered Halo collar on ABC News Live Tuesday, using one dog, Pluto, to show how the device helps train and monitor canine behavior.
The demonstration highlighted the collar’s ability to create invisible boundaries and deliver gentle alerts — whistles and vibrations — as a dog approaches limits set by an owner, positioning the device as a remote training aid that monitors behavior in real time. Emerging products in pet training include AI-powered training apps that analyze pet behavior and offer customized training plans, which some companies promote as a way to enhance the accessibility of behavior modification.
On the air, Millan explained the collar’s role in close, practical terms and likened the device to his own presence. “It’s like me being in a collar and I’m just supervising your dog,” said Cesar Millan, dog behaviorist.
The Halo collar is developed by the company Halo collar, which designs the device to work by setting wireless boundaries and sending feedback when those boundaries are approached. Millan demonstrated how the collar responds with gentle alerts intended to guide a dog back to a safe zone, and described this as part of his training philosophy; some trainers associate such approaches with more humane or positive methods.
During the segment, Millan emphasized consistent owner involvement alongside the technology. “What I see in my 20 years on TV is that people don’t maintain consistency with exercise, walks and runs,” he said, adding a practical note about behavior change: “The more you walk with the dog, the more you connect with the dog.” This aligns with widely promoted recommendations for positive, reward-based training methods; however, major organizations have not specifically endorsed AI tools like this collar in the ABC News reporting.
The demonstration used Pluto as an example of how owners might rely on the collar for day-to-day boundary training and behavior monitoring. Millan described the system as an extension of supervision and training, with the device issuing gentle auditory and tactile cues to shape movement near defined limits, fitting within the evolving landscape of dog training that has transitioned from dominance-based methods to more humane approaches.
Representatives of Halo collar market the device as an AI-assisted trainer that pairs hardware with app-based controls for owners. The on-air demonstration showed the collar’s feedback modes in action and underscored the company’s approach of combining remote alerts with human-led routines. This integration is part of a broader trend that includes wearable and smart-home technologies designed to enhance the training experience.
Millan also stressed calm, measured interaction as part of training. “If you want to change the behavior of a dog, practice a little bit more silence, practice a little bit more calmness, and understand how the mind of a dog works,” he said, framing the collar as a tool that supports those principles rather than replacing them. His insights reflect a growing recognition of the importance of understanding canine psychology in effective training practices.
The segment laid out the device’s basic functions: invisible fencing, behavioral monitoring and real-time feedback through whistles and vibrations when a dog approaches a set boundary. Millan presented those features while explaining how owners should pair technology with regular exercise and consistent routines, which are key to maintaining an effective training regimen.
ABC News viewers saw the Halo collar demonstrated live, with Millan narrating how the system fits into everyday training and supervision. The broadcast presented the device as a way to help owners maintain boundaries and monitor behavior when they cannot be physically present.
