How Does Halo Collar Work?

Below is our personal experience with the Halo Collar including the most recent Halo Collar 3. The setup process for either model is the same.

Halo Collar 3 comes with a USB-C charging cable, a magnetic adapter, and two sets of contact points. These points send vibrations to your dog’s neck when he nears your set boundaries. It also comes with a beacon that you’ll use as a “keep away” zone when indoors and an instruction manual.

Setting Up The Collar

I first needed to remove the collar’s protective fabric case and adjust the strap size to fit my dog. You may need to trim some of the excess rubber off the strap if the collar is too big. It has extra metal end caps and a clamp to put on the end caps. You’ll keep the blank contact points on at first and won’t put the actual contact points on until after training.

I then charged the collar. The newer model has a magnetic port on the USB cable which is less likely to trap debris and dirt. Once the collar was fully charged, I downloaded the Halo app and followed the prompts to create an account, purchase a subscription plan, and activate my collar.

I created a profile for my dog, including his name, birth date, breed, and photo. Then, I connected to WiFi to pair my collar with my phone and then calibrated the collar’s GPS. Each step in the setup process has a video tutorial to guide you along.

If you have any trouble, customer support can walk you through step by step in real-time. I had a live customer support agent who was super nice and helpful in assisting me in getting started.

Creating Virtual Fences

Holding halo collar outside to create fence

Next up, I created my fence. When I walked outside, the GPS tracker noted my location on a satellite image. First, I dropped a pin (or fence post) to set the boundary of the virtual fence area. Then, I continued to drop posts until I created the full perimeter of the area where I want my dog contained. If the dropped pins are not exactly where you want them, you can go into the app and drag and drop them manually by placing them on the map in the app.

I tested the fence boundaries and used the training section of the app to get me and my dog acclimated to the collar’s signals. You can set up to 20 different fence areas or use optional Beacons (battery-operated devices that are used to create “no-go” zones) for when you travel or need to use a different area for a safe zone.

Note: I tested both the Halo 2+ and the Halo 3, and Halo 3 has greatly improved GPS tracking accuracy and less delay on where you and your dog are moving on the map.

Tip: Before getting started with the collar training and feedback settings on your dog, let them sniff it and get acclimated to wearing it for 30 minutes at a time. This allows them to get comfortable with the device around their neck and builds them up one step at a time.


The app walked me through a series of training videos which are super entertaining and informative. The quality is very cinematic, and the text helps reinforce the audio instructions. They even have closed captions for those with hearing impairments. One nice feature is the ability to watch the videos on a computer or iPad (without logging in) so I could use the Halo app on my phone to set up and train.

The first three lessons are basic user training, followed by basic pet training. Lessons 4-12 show you how to use the collar. After each video, a quick quiz tested my knowledge to make sure I fully understood how to use the collar. Even Cesar himself makes a few appearances. You can pause and rewind at any time in case you missed something or need to hear it again.

After learning about types of feedback (prevention and encouragement), I worked on beacon training. This gets your dog accustomed to feedback in a safe, indoor setting. As suggested, I used a high-value treat (like cheese, bacon, or other “special” or smelly treat) to entice my dog near the beacon.

You’ll manually give your dog feedback (sound or stimulation) and a reward to guide them away from the “no-go zone.” You’ll repeat these steps several times for 30 minutes and do at least 3-4 sessions before building up to outdoor boundaries. Eventually, when you turn the beacons on, the beacon will automatically give feedback when your pup gets within a certain range of the no-go zone.

In addition to training your dog on boundaries and using positive reinforcement for feedback (either automatically in the zones you create or using the app to manually give feedback to your dog or signal “safe” at home), you can use the collar to watch a library of training videos on other commands or training tasks. The app also tracks your dog’s activity, keeps a “score” of how well they react to feedback, and more.

What’s Our Final Verdict?

Visit Halo Website

The Halo Collar GPS system has multiple tools in one, including GPS location tracking, behavioral training, and activity tracking. Its original version had mixed customer reviews with complaints about collars breaking, unreliable GPS location, false positive alerts, etc. However, the company listened to its customers and made a variety of improvements to address these issues, launching Halo Collar 2 in late 2021, Halo Collar 2+ in mid-2022, and the newest Halo Collar 3 in fall 2023.

The reviews of the newer collar are still mixed in terms of reliability and accuracy for GPS fencing. However, the collar itself works as a good training tool and can get your dog accustomed to using a smart collar with expert videos and support.
