Halo Collar by Protect Animals With Satellites, LLC. Introducing Halo: the world’s greatest smart fence system. We know how important it is for pet parents to know their dogs are safe, and we saw that there were no solutions out there that did it all. So we've created Halo: the only smart fence system that allows you to create virtual fences (that actually keep your dog inside) at the touch of your finger, train your dog using Cesar Millan's virtual training program, track your dog's activity and safety statuses, and instantly communicate with your dog anywhere. Halo Fences eliminate the need for messy and expensive digging and burying wires that can be cut or damaged to give pet parents freedom and peace of mind. You can create up to 20 unique Halo Fences virtually anywhere in the world, right from the Halo App. Using our advanced global satellite GPS/GNSS systems, you can create smart fences at home, a friend's house, the dog park, the beach...the options are endless. Halo Fences are saved right in your dog's collar, so you never have to worry about your Wi-Fi or cellular coverage affecting their safety. No more settling for notifications after your dog is in danger. Halo Fences work autonomously, providing the customizable feedback you set for your best friend at exactly the right time to keep them safe...and can even bring them back home! Our mission is to bring safety, communication, and freedom to dogs and pet parents everywhere
