Halo Collars receive four GPS updates per second, so you see your dog’s location in real-time all the time in the Halo app.

A dog can run more than 30 ft in 1 second, so more frequent location updates means you know where your dog is and that they are safe.

Always-on GPS with drift prevention, that uses our AI software to filter interference from obstacles.

Halo's independently verified GPS chip offers unparalleled accuracy within 1.4 ft of their true outdoor location.

Other Details


Will Halo work for my dog’s breed?

Yes! Today over 350 breeds are currently using Halo Collar. Halo is a proven system that works on any breed and any age, as long as they are over 5 months old and over 20 lbs. It doesn’t matter if your dog’s breed is stubborn, energetic, playful, or calm, or if they chase squirrels, like to swim or frequently visit your neighbors. Once you train your dog on Halo, it will work on any breed.

Can Halo work with multiple dogs?

Each dog needs their own Halo Collar, but all dogs can be managed through one account in the Halo Collar app. Each collar can use all Halo Fences that are created and can be turned on/off for each dog without affecting the other dog(s) on your account.

There is a multi-dog discount applied for a purchase of two or more Halo collars and the additional collars are discounted on your Pack Membership plan.

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.

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.

Can the Halo Collar be worn in the water?

Yes, the Halo Collar has been through significant testing, including submersion, swim testing, and saltwater testing.

How accurate are Halo Fences compared to other “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 addition, Halo Fence posts can be placed anywhere, and are not limited by geography or other obstacles that prevent the installation of a wire.

How has Cesar Millan been involved in the design of the Halo System?

Cesar Millan is the world's foremost expert in dog psychology, so everything the collar does, how it does it, and even the way the Halo Collar looks, have been designed in collaboration with Cesar.

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.

Who will train my dog? How long will that take?

It's highly important that you are the one who trains your dog. Every dog needs a pack leader, so as a pet parent, that pack leader needs to be you! This will not only help with your Halo training, but will build the trust, respect, and love that is essential for a happy life with your dog. On average, pet parents should expect to practice for at least 15 minutes a day for about 21 days—enough time to build a strong habit. Every dog learns at different speeds, so it may take more or less time. Make sure to be patient with your dog, and they will learn much more quickly!

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!

If I already own an invisible dog fence, how much training for the Halo Collar is required?

If your dog is already trained on another fence system, Halo can use the same sounds and settings that your dog has already learned. Your dog may understand immediately—but make sure to practice, and check that your dog understands your new boundaries! With Halo, you can even take the fence with you!

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.

Is there a limit to the number, location, or size of Halo Fences I can create?

You can create an unlimited number of fences in your Halo app depending on your plan, and they can be created anywhere in the world. If you intend to go to a zero-coverage area, you can set up your Halo Fences before you leave, and it will work seamlessly. You can edit any fence, at any time (just be sure to practice this new boundary with your dog!). Each fence needs to include a minimum of 30x30 square feet for your dog to roam safely, and can accommodate a maximum of over one thousand square miles.

What is a Beacon?

Beacons are small devices that automatically communicate with your Halo collar when they are nearby each other - even indoors.

The Zone Beacon, USB Beacon and Training Beacon can be set to one of two modes in your app: “Keep-Away” mode or “Ignore Fences” mode. “Keep-Away” mode is used to keep your dog out of unwanted or unsafe areas by simulating the presence of a Halo Fence boundary. “Ignore Fences” mode can be used to create a portable ‘safe’ zone where your pup won’t receive any Fence feedback.

The Remote Beacon can give your dog instant feedback of your choosing with just a push of a button instead of going into the Halo app.

Does Halo work with iPhone and Android?

Yes, and you can download the Halo Collar iPhone app from the App Store or the Google Play store.

Why do I need a Pack Membership Plan?

A plan is required to keep your collar active and access all your Halo collar has to offer. All Pack Membership Plans come with unlimited cellular data and automatic network switching on most cellular providers (AT&T, Verizon, T-mobile, and dozens more worldwide), so you can have continuous GPS with real-time location tracking and alerts. As long as your Plan remains active, Halo will provide all of your subscribed services and will also provide you with live support along the way.

How do I change my plan?

Log into My Account on On your My Account page, you will be able to change the number of collars, change your membership level, add Halo Care and change your billing cycle.

Once your Plan is activated, some Plan changes can take effect immediately, while others can only be scheduled for the end of the current billing cycle. You will see this clearly stated, and be asked for confirmation, prior to making any change.

Do I get a discount on a Pack Membership Plan if I have more than one collar?

Yes! Not only do we offer a discount if you purchase two or more Halo Collars, but we also offer significant savings on your Pack Membership Plan for additional collars. If you have a Bronze level membership, an additional collar will only cost $3.99/month. If you have a Silver or Gold level membership, an additional collar will cost $4.99/month.

How does annual billing work on a Pack Membership plan?

Halo offers an annual billing option that discounts your entire Pack Membership Plan by 15%. That includes a discount on the Plan cost for additional collars and even on Halo Care.

You can switch at any time from a Monthly billing cycle to an Annual billing cycle from your My Account page. This will immediately start you on an Annual plan. If you are already on an Annual plan, a change to Monthly will be scheduled for the end of the annual billing cycle.

Can I cancel my plan?

You can cancel your plan for a refund for any reason prior to activating your first collar. Once you activate your first collar using the Halo app, your Plan will officially Activate, and will remain active through the end of the current billing cycle. You may cancel prior to Activation, or submit a cancellation request for the end of the current billing cycle, by logging into My Account, clicking on Account/Edit Account Settings/Membership, and following the cancellation procedures described there.

I don’t have a yard of my own, or I live in an apartment, rental home, condo or townhome. Can I still use the Halo System?

Of course! One amazing part of Halo is the portability and freedom it provides. You can set up Halo Fences instantly in any location: at a rental property, around your apartment building, at a family member or friend's house, the park, the beach—the opportunities are endless! In addition, Halo Beacons can be used anywhere inside to provide indoor support, and your Cesar Millan training will teach you how to be the best pet parent possible.

Will Halo work when I am out of cellular or Wi-Fi coverage (i.e. while camping or hiking in a remote location)?

If you intend to go to a zero-coverage area, you can set up your Halo Fences before you leave, and it will work seamlessly. Halo Fences are stored in the collar's memory and won't be lost even if/when it loses power or an internet connection.

Does Halo work indoors?

Yes! Indoors, the Halo Collar can prevent dogs from entering unwanted or unsafe areas. To do so, set up Bluetooth-based Keep Away Beacons that trigger fence-like alerts when your dog comes near them.

Will it work worldwide? Is it available for sale outside of North America?

All dogs speak the same language! Halo will work anywhere. But to make changes or see real-time updates, you need Wi-Fi and/or cellular coverage. We are starting in the United States but will expand to other countries soon.
