How Halo Works
The Halo Collar
Your dog’s personal halo of protection. Fences are stored right on the Halo Collar and autonomously guide your dog to stay inside—even without wires, WiFi, or cellular.
The Halo App
Your hub for everything Halo. Create up to 20 wireless fences, access training, view your dog’s real-time safety status, and manage each dog’s custom preferences at home or on-the-go.
Access Cesar’s custom 21-day Program, special training features, premium lessons, and live sessions with expert trainers.
The Halo Collar
Your dog’s personal halo of protection.
Halo Fences use world-leading GPS & GNSS instead of wires, and they’re stored directly in your dog’s Halo Collar. Fences work automatically to keep your dog inside. You never have to worry about your WiFi or cellular connection affecting your dog’s boundaries.
Easily create up to 20 fences in minutes by tapping on your map, or by walking the perimeter with your Halo Collar. You can edit your fences any time—no wires, no digging, no damage, and no range or terrain limitations.
The Halo Collar communicates with your dog using customizable Prevention Feedback at the right time. Fences calculate when your dog is near the boundary to prompt them to turn around. As soon as they stop or turn back, the collar even uses Encouragement Feedback to say ‘good job’!
With a wide range of sound, vibration, and optional static prompts to choose from, you can customize your dog’s feedback to perfectly match their learning style. Set your pup’s profile color and matching Halo LED, which signals collar mode changes and lights up for nighttime-visibility
The Halo Collar is one-size-fits-most, with a flexible comfort fit. Choose a replaceable strap in Small, Medium, or Large. The Halo Collar’s custom strap with clasp and no-slip grip can be easily adjusted or swapped out for a larger size as your dog grows.
Advanced multi-constellation satellite systems overhead communicate with your Halo almost anywhere in the world. Custom, durable materials and rigorous environmental testing keeps your collar ready for any adventure—even featuring an IP67 water rating for peace of mind in any weather or water.
The Halo App
Your hub for everything Halo.
Fully-closed virtual safe areas that allow your dog to safely roam off-leash inside the Halo Fences you create, so you and your dog have freedom and peace of mind any time, anywhere.
Safety Status & Location
Real-time GPS & GNSS reporting lets you check your dog’s safety status and location, or watch live location updates with Bluetooth™ enabled and while in range of your Halo Collar.
Manage Fences & Beacons
Create, edit, pause, and enable boundaries for all of your fences and beacons. Easily adjust preferences with a tap, with the ability to change modes for one pet or multiple pets at a time.
Track Activity & Progress
Daily, weekly, and monthly activity charts track how much time your dog spends active vs resting, how many Preventions they receive, and where–so you always know about your dog’s safety, activity and training progress.
Everything you need for the best training experience in one place. Manage your dog’s custom feedback settings, access your 21-Day Program from Cesar Millan, and opt in to premium lessons to master all kinds of training techniques.
