If your dog escapes beyond the three levels of protection provided inside your Halo Fences, there are multiple fail-safes outside of your fences that will help protect your dog. You will immediately be notified if your dog has escaped. In addition, with Cesar's expert guidance, you will train your dog to come right back home! Your dog's Halo Collar will use its advanced algorithms to intelligently determine which direction your dog is facing, so that they only receive prevention feedback if they keep running further away from safety, and so they'll never receive a correction while heading home!
