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. Please visit www.halocollar.com for more information about the Halo Collar. Recommended minimum OS version is iOS 16.
