To measure your dog's strap size:

  • Place a tape measure (or a string) around your dog's neck, and hold both ends together
  • Ensure that you are measuring high on your dog's neck, but still underneath their chin and ears
  • Tighten the tape measure until you can fit 2 fingers comfortably between the neck and tape measure
  • Check the length on your tape measure and match to the corresponding size in the chart
  • Your dog's collar strap can be adjusted according to their best fit once you receive their Halo Collar
  • What will Halo look like on my dog?

Advanced GPS/GNSS allows you to create the most accurate wireless smart fences using your Halo collar's built-in GPS OR with the tap of your finger in the Halo App.

Save up to 20 unique, installation free wireless fences for less than the cost of one in-ground wire fence. Once your fence is saved and synced, your dog's Halo automatically guides them to stay inside—so no need to worry about Wi-Fi or cellular interruptions affecting the boundaries you create.

Our expert training program is designed by Cesar Millan, and teaches you how to safely train your dog using positive associations. You'll learn to set customizable feedback using sound, vibration, and (optional) static that's just right for your dog's learning style.

Frequently Asked Questions 

How is Halo different from other “smart” collars?

Halo is the safest and most advanced virtual fence for your dog. But Halo offers so much more than any other e-collar. Halo Fences keep your dog safely inside the boundaries that you easily define, and prevents them from leaving (unlike other tracking collars, which only track and notify you when they escape).

It also keeps track of the activity levels and exercise that result from the freedom the fence provides. Your Halo Collar prevents, protects, tracks, and trains your dog—and can even guide your dog home.

How Accurate Are Halo Fences Compared to "wired" fences?

The Halo Collar’s advanced GPS/GNSS system is extremely accurate. It uses the latest geolocation technology and is more accurate than your smart phone. Halo Fences are not created using a wire, so they can’t be cut, damaged, and don’t need to be installed underground. In additon, Halo Fence posts can be placed anywhere, and are not limited by geography or other obstacles that prevent the installation of a wire.

Can the Halo Collar be worn in the water?

Yes, the Halo Collar has been through significant testing, including submersion, swim testing, and salt water testing. It can be worn in any weather, or when your pup is ready for a splash or a swim!

Does Halo use static feedback? When is this feedback useful?

Static feedback provides a sense of “touch” that feels like a tap on the shoulder for your dog. This interrupts 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, and it is entirely optional. However, some dogs respond best to static feedback for a variety of reasons. Some dogs simply don’t feel vibrations through thick coats or due to their high level of focus. Other dogs actually find it to be far less surprising than vibration prompts! This is because it creates a pulsing sensation that simulates a sense of touch, whereas vibration creates a buzzing sensation with a sound. 

The Halo training process will help you customize the feedback that your dog will respond to, based on their personality and learning style. 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 safe.

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

When approaching a boundary, your dog will receive a customizable warning. This activates your dog’s associative memory, and your dog will learn that a warning means “keep away” from the boundary and “come back” to safety. Warnings simply serve as reminders to turn back around toward home! After that, two more tiers of preventions (Boundary, then Emergency Feedback) are applied if your dog is distracted and ignores the boundary.

Each of the three types of preventions are completely customizable according to your preferences and your dog’s learning style.

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

The Halo Collar will last for 10-14 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.
