# Halo Collar

> Halo Collar is a GPS-powered smart dog collar that replaces the buried-wire invisible fence with virtual boundaries you draw on a phone. Co-founded by industrial-IoT veteran Ken Ehrman, his brother Michael, and celebrity dog behaviorist Cesar Millan, the Plano, Texas company sells the hardware direct-to-consumer with a required monthly membership, and pairs GPS containment with Millan's training method. It says more than 200,000 dogs across roughly 350 breeds now wear one.
