Smart Fences

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.

No Installation

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 timeno wires, no digging, no damage, and no range or terrain limitations. 

Natural Guidance

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’!

Customizable Settings

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

Flexible Fit

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.

Go Anywhere

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 adventureeven featuring an IP67 water rating for peace of mind in any weather or water.
