An all-in-one dog fence, training, and tracking solution, utilizing smart technology and natural dog psychology from renowned dog behavior expert, Cesar Millan.

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.

My friendly and fun-loving golden-doodles were very spotty in staying at home. I live in a wooded area and had to leave my dogs gated on my large porch most of the time since they would often run off to explore the woods. Sometimes being gone for half a day. This was not safe for them and caused a lot of stress for me.
After a lot of research, I finally broke down and invested in two Halo collars. They were both refurbished. On delivery, one initialized perfectly while the other did not. I used the Dog Park option and had a video call with a rep right away to resolve the issue. Super support team and function of the Halo app. I did end up having to replace the one collar due to an issue with it not track correctly. The return process and easy and had a replacement within a few days. The replacement is working great.
The training process was a little off-kill for my dogs since I had already done some basic training with them. I did most of the recommended training with one dog and found it became more confusing to her because of the previous training. So after some basic training to associate them to the collars , I let them loose and both adapted great to the recall and mild correction. Now they have no static correction and are very responsive.
They are free to roam the property and know their boundaries and are very happy dogs. I’m am stress free. It was working the investment!

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.

Great concept

UPDATE: After getting a replacement for our first one because the battery was crap, well the new one maybe even worse, I take the collar off the charger and it says 13 hours (which is terrible) the dog has it on for an hour and it’s at 5 hours left, like really?!?!? I will say the gps works better on the new one I don’t have to calibrate it as much (knock on wood). I’m still giving it a 2 star for the battery it is nothing what it is advertised which is 19 hours.

We have had this collar for about 2 weeks, we live on 6 acres so this was easier than trying an invisible fence that you would need to bury the fence. My dog knew right away not to go past the boundaries and when the collar works it’s a fantastic product. My problem is it loses it calibration a couple times a week, it has him completely out of the fencing zone a mile away and he is literally right outside the door so that is very annoying. My next problem is the battery, it advertises 19 hours, well let me tell you mine barely last 5 to 6, I let it charge overnight just like the instructions tell you too take off the charger and it will say 12 put it on the dog 5 to 6 so I order for me to make it all day I am having to charge it during the day, it’s very frustrating. Customer service has not even responded to my questions. For as expensive as this collar was I guess I expected the product to be a bit better than this, I’m really kind of disappointed.
