Halo Collar gives dogs the freedom to roam — with boundaries that can travel with you. Using dual-frequency GPS, Halo creates wireless fence boundaries anywhere, with no buried wires and no physical barriers. The patented boundary system stores fences directly on the collar, reads which direction your dog is heading, and responds with smart, escalating feedback that works just as well at a remote campsite as it does in your backyard. No Wi-Fi or cellular required.
Virtual GPS Fencing is the core boundary technology built into every Halo Collar. It uses dual-frequency GPS (L1 + L5 bands) and Precision+ (DGNSS) to locate your dog and enforce fence perimeters with independently verified accuracy within 0.6 meters of your dog's true outdoor position.
Unlike traditional buried-wire fences that are tied to a single property, Halo's virtual fences are created in the Halo app and stored directly on the collar — so it works wherever your dog goes, whether that's a rural property, a campsite, or an off-grid vacation home where Wi-Fi and cellular signals don't reach. Halo Collar 5 determines your dog's position 20 times per second, the highest GPS update rate among GPS dog fences currently available.
Explore all Halo Collar features including real-time tracking, health monitoring, and the Cesar Millan training program.
Every part of Halo's GPS fencing system is designed with one goal: keeping dogs safely within their boundaries intelligently, reliably, and humanely.
Search an address or drop a pin anywhere on the map in the Halo app. One tap generates a GPS fence aligned with actual property boundaries - no surveying equipment, no wire burial, no professional installation. Fences can be as small as 900 square feet or as large as 1,200 square miles, and any boundary can be adjusted or reshaped manually after creation.
The Halo app manages unlimited independent GPS fences at once. Boundaries can be set at home, a relative's property, a campsite, or any off-leash area — and each fence can be individually paused, reshaped, or re-enabled without affecting the others.
All boundary coordinates are saved to the Halo Collar’s onboard memory. The collar’s built-in dual-frequency GPS receiver (L1 + L5 satellite bands) calculates your dog’s position independently, supported by Precision+ (DGNSS) which enhances the satellite data using data from nearby ground stations. In addition Halo’s proprietary AI software filters interference from buildings, trees, and other obstacles. Your dog remains protected even in areas without Wi-Fi, cellular signal, or phone proximity.
Halo's patented feedback system includes six response types: three that prevent boundary crossings (Warning, Boundary, and Emergency) and three that encourage the right behavior (Whistle, Good Dog, and Go Home). Feedback only escalates when a dog continues moving toward or beyond the fence boundary — and it doesn't stop until the dog responds. Once it responds, encouragements bring your dog back to safety. With customizable voice commands, tones/sounds, vibration patterns, and optional static levels, owners have complete control over how their dog experiences the system.
The collar tracks whether a dog is heading toward or past the boundary or already turning back toward the safe zone. If the dog is already returning, the collar doesn't escalate — no unnecessary corrections, no confusion. Halo's patented directional logic makes sure the dog gets exactly the right response at exactly the right moment.
Once a dog reverses direction in response to the boundary, the collar plays an audible "Come Back" cue reinforcing the right behavior automatically, without any action needed from the owner. This cue is part of Cesar Millan's step-by-step training program included with every Halo Collar.
Other GPS fences respond the same way every time a dog gets close to or crosses a boundary, whether the dog is sprinting toward the edge or already turning back, leaving your dog confused. Halo's patented direction-detection system knows the difference. The Halo Collar reads which direction the dog is facing and whether they're moving toward or away from the safe zone in real time. That means no unnecessary corrections, less confusion during training, and a solution that builds genuine connection.
A gentle warning tone begins when the dog enters the boundary zone.
Escalating feedback activates if the dog keeps moving toward the boundary.
The collar plays "Come Back" and stops all feedback immediately.

Whether the property is a sprawling rural ranch or a compact suburban yard, Halo's GPS fencing adapts to where the dog actually lives and where they go.
HOA restrictions keep many neighborhoods free of visible fencing. Halo's virtual GPS fence creates a real boundary around a property with no posts, no wires, and no visual footprint on the landscape.
A new GPS fence can be created at your rental/vacation home, a campsite, or a friend's house in under one minute. Fences stay stored on the collar, so switching between locations is automatic.
Buried-wire fences become expensive and difficult to maintain on large properties. Halo supports boundaries up to 1,200 square miles and works in areas where cellular coverage is spotty or nonexistent, the collar enforces boundaries on its own using stored GPS coordinates.
Each dog wears their own Halo Collar, and all collars share the same fence boundaries through a single account in the Halo app. Fences can be toggled on or off for individual dogs without affecting the others. A multi-dog discount is available on collar purchases.
A dog can cover more than 30 feet in a single second. Faster location updates translate directly to faster boundary response — Halo's 20-updates-per-second GPS detects a high-speed approach and begins the warning sequence before a slower system would even register the movement.
Halo includes a structured training program built with Cesar Millan — lessons that teach dogs to recognize and respect fence boundaries through positive association, not punishment. Every dog learns at their own pace, and the program lives right in the Halo app to guide owners through each step.
Download the Halo Collar app for iOS or Android. Navigate to the Fences section and tap "Create New Fence." The app loads a satellite view centered on the current location.
Use one-tap creation to generate a fence based on property lines and Halo Fence guidelines. Or place fence posts manually with a tap to draw a fully custom boundary shape. Any fence can be adjusted, resized, or reshaped at any time.
Fence coordinates transfer directly to the collar via Bluetooth. Once synced via the collar's Wi-Fi or LTE connection, the boundary is stored in the collar's onboard memory and works independently — no phone, no Wi-Fi, and no cellular signal needed.
This walkthrough shows one-tap fence creation, the patented escalating feedback system in action, and how the automatic "Come Back" command guides a dog back to the safe zone when they respond to the boundary.
★★★★★“It took me some time to decide, but upgrading from Halo 4 to Halo 5 was a great decision. The GPS is amazing and I love that I do not have to charge it every day. It makes me so happy to see Mason playing, I never worry where he is because he always stays inside his boundaries. Everyone should get a Halo Collar!!”
★★★★★“I’m so impressed with Halo 5! The previous models were good, but this one blows me away. The GPS responds quicker, I have had no missignals when the dog is in the house, and the battery life is incredible. One night I forgot to put it on the charger and the next morning I still had 26 hours of battery life. I love all of the improvements!”
★★★★★“I live on 5 acres with a male 8-yo Chesapeake Bay Retriever. I have been using Halo 5 for nearly two months now. The battery life is phenomenal! After 15 hours of use I still consistently have 15 hours or more of battery left when I put it on the charger every night. There has been no gps drift and no false corrections and no problems with my dog swimming in the pond daily. It keeps him on the property and I can just check on the app for his exact location. I love how they make it easy to adjust the collar to fit my dog.”
Halo Collar stores all fence boundaries directly on the collar hardware. The built-in dual-frequency GPS receiver calculates the dog's position relative to those stored coordinates — GPS works independently of connectivity. As long as the collar can detect movement toward the fence, boundary feedback occurs. Dogs stay protected even in remote locations with no internet access whatsoever.
Yes. Halo's one-tap fence creation uses satellite imagery to generate boundaries aligned with real property lines. Any fence can be adjusted, resized, or reshaped manually in the Halo app after creation, and custom polygon shapes with unlimited points are fully supported.
Halo uses a patented escalating feedback system with six customizable types: three that prevent boundary crossings (Warning, Boundary, and Emergency) and three that reinforce the right behavior (Whistle, Good Dog, and Go Home). Owners can choose from sounds, vibration patterns, and optional static levels — including Cesar Millan's voice commands. Feedback only intensifies if the dog keeps moving toward the boundary. The moment they turn back, the collar plays an automatic "Come Back" command and all prevention feedback stops.
There's no limit. Unlimited virtual GPS fences can be created and managed from the Halo app, each individually paused, edited, or enabled at any time.
Yes. Halo's direction-detection technology reads whether a dog is moving toward or away from the boundary. If the dog is already heading back to the safe zone, the collar doesn't escalate — eliminating unnecessary corrections and keeping training clear and consistent.
Yes. Halo is not a shock collar. The system is built around positive training principles developed with Cesar Millan. Static feedback — when enabled — delivers a gentle sensation, similar to a tap on the shoulder, and is always optional. Many dogs respond to sound or vibration alone. Feedback is gentle, progressive, and always paired with an encouraging "Come Back" audio cue. Owners choose the feedback types and intensity levels that work best for their dog, and the included training program introduces boundaries gradually and positively.
Yes. A Pack Membership Plan is required to activate GPS services, create and edit fences, and maintain cellular connectivity — similar to how a smartphone requires a data plan. Plans start at $9.99 per month and include LTE data for real-time tracking, firmware updates, and access to all app features including activity tracking, health monitoring, and instant recall.
Halo Collar works for any breed and age, provided the dog is over 5 months old, weighs at least 10 lbs, and has a neck size between 8 and 30.5 inches. Over 350 breeds are currently using Halo Collar — from high-energy working dogs to calmer companion breeds. Once trained, the system is effective across a wide range of temperaments and energy levels.
Halo GPS fences range from 900 square feet (roughly 30 × 30 feet) to 1,200 square miles. The 900-square-foot minimum makes Halo one of the few GPS dog fences genuinely suited to smaller suburban properties. Fences can't be cut, jumped over, or dug under — and they require no physical upkeep.
Halo Collar 5 is IP67 waterproof and operates in temperatures from –22°F to 140°F, so rain, snow, and heat don't affect the hardware. GPS signal can be reduced under dense tree canopy or near tall buildings. Halo's AI software is designed to filter that interference and reduce drift. For heavily wooded properties, setting a slightly wider buffer zone around the boundary is recommended.
Both Halo and SpotOn offer dual-band GPS, direction detection, and portable virtual fencing. The key differences: Halo supports fence areas as small as 900 sq ft (SpotOn requires a ⅓-acre minimum), includes Cesar Millan's structured training program, offers six feedback types including voice commands, and provides Halo Health™ activity tracking. SpotOn doesn't require a subscription for basic fencing. Halo's Pack Membership Plan ($9.99/mo) bundles cellular tracking, firmware updates, and full app access. For a detailed side-by-side, see Halo Collar 5 vs. SpotOn Fence.
Halo Collar 5 with Virtual GPS Fencing is available now. Wireless boundaries that go wherever the dog goes — with dual-frequency GPS accuracy, patented direction detection, and protection that works without wires, walls, or Wi-Fi. Trusted by more than 500,000 dog parents.
