Combining smart technology + Cesar Millan's expert dog psychology to create the world's greatest all-in-one smart fence, tracking, and training solution for dogs

Introducing Halo: the world’s greatest smart fence system. The virtual fences you create right in the app work with the revolutionary Halo Collar, and actually keep your dog safely inside. Halo also includes in-app expert training, using Cesar Millan's proven training methods, real-time safety and activity tracking, and instant communication with your dog anywhere to provide the best protection for your best friend—at home or on the go.

Halo Fences
The easiest fences you’ve ever set up: it’s as simple as tapping on your map in the Halo App, or by walking around the boundary you want to create using the Halo App and your Halo Collar. Halo Fences use world-class global satellite GPS & GNSS systems to locate your dog(s), and work autonomously to provide instant Prevention and Encouragement Feedback to keep them safely inside their smart fences, direct them back in if they leave, or call them back home wherever they are. Halo Fences are stored right inside the Halo Collar, and don’t rely on a cellular or Wi-Fi connection to work. If your dog approaches a Halo Fence boundary, they’ll instantly receive guidance to teach them where they can and cannot roam freely.

Easy Setup, Unlimited Options
No wires, no digging, and no hubs necessary. Halo Fences are created in the Halo App, then sent to and stored inside each Halo Collar. You can even create up to 20 unique Halo Fences virtually anywhere in the world. Finally, a fence that your dog can’t jump over, dig under, and that won’t let your dog run out of range, regardless of terrain, property ownership, and the size and shape of your fences.

Intuitive Boundaries
Halo Beacons are small Bluetooth beacons that communicate with your dog’s Halo Collar just like Halo Fences do. Place Halo Beacons indoors to keep your pup out of harm’s way from dangerous areas like stovetops, or off-limits areas like trash cans. Halo Beacons and Halo Fences provide instinct and consistent guidance from the Halo Collar, and can easily be managed right from the Halo App.

Phone Notifications
Stay up-to-date, but not on the edge of your seat. With in-app and push notifications, you’ll stay in the loop about your dog’s safety without having to worry that you’ll need to panic and rush to bring your escape artist back home.

Completely Customizable
Completely customize your dog’s feedback directly in the app. Preventions (Warning, Boundary, then Emergency) communicate the existence of a boundary that your dog should keep away from. Your pup will only receive Prevention Feedback while moving toward danger; as soon as they stop, turn around, or head back home, the Halo Collar’s advanced internal logic plays customizable Encouragements to tell your dog they’re doing a great job. It even automatically plays a Return Whistle to guide them back home!

Revolutionary Training
Learn Cesar Millan’s expert techniques to train your dog(s) to recognize boundaries. Cesar’s step-by-step instructions explain his world-renowned, proven methods that will give your dog the safest and most effective training experience anywhere—starting in your home before moving outside. Halo is your go-to pet parenting support that you can count on to give you peace of mind and an amazing relationship with your dog(s)

Real-Time Safety Statuses
No other collar does it all like Halo. Real-time safety statuses tell you whether your best friend is safe at a glance. And fast and accurate tracking via GPS & GNSS, Bluetooth, Wi-Fi, and cellular technology shows you what your pup is up to, even if you’re not around.

Activity Tracking
Activity tracking logs your dog’s location, number of walks per day, and time spent active, resting, or in the car. Keep up with how much exercise your dog is getting every day so you can stay on top of their health goals.

Very Functional and Extremely Happy

We purchased this as a lower cost solution to a wired in usable fence. We camp (boondock) a lot and being able to create a fence around our remote site has been a fantastic experience with piece of mind. Our dog is usually not far out of sight while camping due to snakes and other wild animals but at home he has a few acres to roam free. I can look on the app and see where he currently is but I do not worry as I know the app will notify me if he tries to breach a boundary. So far he has only been warned once at home with the sound. He knows this sound so well that it does not need to escalate to the vibration or static correction.
It has also been a valuable tool in training as he is only 7 months old. We started using this over 2 months ago. I can manually give him the whistle feedback and have trained him to come find me when he hears it.
We did have a hardware issue where the collar stopped connecting to WiFi and cellular. Tech support was outstanding and they helped walk me through the submission of their RMA process to have a new collar shipped out right away.
So far Halo has made great updates in firmware and app releases.
Looking forward to years of use and keeping my dog safe.

All in one solution and more!

We got the halo color for my one-year-old shepherd mix who loves to be outside. We have invisible fence but had multiple breaks of the line, each of which cost us time and money to fix. We also had a scary event where she broke out of my wife’s grip because she bolted after a deer on a walk in the woods. Luckily she came back (eventually), but we wanted to be sure we had a fail safe.
The Halo solved all of our issues. On our property, it functions exactly as our fence does; I walked our property to set the border and it mirrors our existing invisible fence, functioning exactly like it so no training was required. While on walks, I am able to track her down to a couple of feet; thankfully this has not been necessary to use at this point.
What I really love about the car is the extra things that we get out of it. I am teaching her to walk off leash and the collar, along with the training modules are helping me along. Also, when I take her to someone else’s property, I can set a new fence that she will stick to so we have great playdates!
Halo was a great solution for us, I love that we can use one device for all of our training. For our last dog I bought many separate items and it was much more money overall so this is also a great deal.

Not accurate - but potential game changer

Right now the GPS on my collar is not accurate enough for me to put this on my dog. In some cases the collar location is off by more then 10 yards (yes, YARDS). I have also observed the collar giving boundary warnings when we are well inside of the “fence” and heading towards home. This shouldn’t happen per the instructions and is very confusing for the dog. Using the indoor training beacon, I experience similar problems of inconsistency. At times my puppy can literally touch the beacon with her nose for a few seconds before it goes off, other times it goes off at the right time (1-3 feet per the instructions) but continues giving warnings when she is more then 10 feet away and fleeing from the sound. On the good side, my dog responds to the collar’s signals with incredible consistency. The return whistle sound has become my best recall command. I have been told that a new firmware will be pushed to the collar in the next few days that should solve these problems (I have 0.1.42 right now). I will update this post with details after the update. Also, customer service for me has been great! The team is responsive and you can tell that they care. We are in a testing phase right now so I understand some of the issuesAnd I’m happy to be part of a group trying to get them straight because if this works it will be a game changer for me!
