How does Halo keep my dog safely contained inside my Halo Fence?

When approaching a boundary, your dog will receive a customizable warning. This triggers your dog's associative memory, and your dog will learn that a warning means "keep away" from the boundary. Two more tiers of preventions are applied if your dog is distracted and ignores the boundary.

What are Halo Fences and how do I create them?

Create a Halo Fence in your app by placing fence posts with your finger, or by walking with your Halo Collar to use the collar's GPS. The GPS coordinates of the Halo Fence are automatically downloaded to the collar and remain there permanently (unless you edit or delete them). Halo Fences can't be cut, damaged, jumped over, dug under, and don't require any maintenance.

What types of feedback does the collar provide for my dog?

The Halo Collar is capable of providing six types of feedback:
  • Prevention feedback: Warning, Boundary, and Emergency
  • Encouragement feedback: Good Behavior, Return Whistle, and Heading Home
Each type of feedback has predefined default settings, but you can customize your dog's settings at any time. Your dog's feedback types can be set to use sounds, vibrations, or static. With the variety of sounds, vibration patterns, and static levels to choose from—including Cesar's various voice commands and his famous "TSCH" sound—you have complete control over customizing your dog's experience. With Cesar's guidance, you'll learn to set the best feedback for your dog's energy levels.

Does Halo use static feedback? If so, when? Does it hurt?

Halo uses Static feedback that creates a sense of "touch" meant to mimic a tap on the shoulder (as opposed to shock collars which use an electronic pulse that is painful to your dog). This timely touch breaks your dog's fixation in dangerous situations and distraction-filled environments to keep them out of harm's way. You're never required to use static with your dog's Halo Collar—the Halo training process will help you customize the feedback that your dog will respond to. With a range of static levels available, you can provide the right tap-on-the-shoulder effect that is most appropriate to keep your dog comfortable and safe.

What if my dog escapes the Halo Fence?

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!

How often should I recharge my Halo Collar and what is the expected battery life of the collar?

The Halo Collar will last for up to 24+ hours on a single charge, depending on factors such as having the most up-to-date firmware and how much time you are spending in the app. You should remove the Halo from your dog each night, and charge it overnight so you can start the next day with a full charge.
