Protect your dog with the Halo Collar Wireless Dog Fence GPS Tracker & Activity Monitor Dog Training Collar. Build wireless fences instantly with just a few finger taps on the Halo Collar App and access the fences anywhere you go—even without Wi-Fi or cellular connection. The latest version of the Halo collar is the first and only GPS dog fence that combines data from L1 and L5 GPS bands for the most accurate locations that aren't impacted by obstacles even in urban or bad signal areas. Halo’s training program is developed by renowned dog behaviorist Cesar Millan and includes multiple customized feedback choices to keep your pet safe inside any boundary.

• Safety everywhere you and your dog go: Halo's wireless pet fence keeps your dog safely inside the boundaries that you easily define and prevents them from leaving. Simply draw the boundaries on your smartphone.
• Dual-frequency GPS: Halo uses dual-frequency GPS which combines L1 and L5 GPS bands for accurate locations that aren't impacted by obstacles even in urban or bad signal areas.
• Real-Time tracking keeps you in the know at all times: The up-to-date, real-time location tracking lets you know exactly where your pup is at all times. The wireless dog fence system also tracks activity and resting time, unlike a standard dog training collar.
• Easy setup & training with the Halo App: Video tutorials and 1:1 help from a live customer service team guide you step-by-step to get your collar fence system set up. Instantly create and store wireless dog fence perimeters at the touch of a finger in the Halo app.
• A Pack Membership Plan is required: Your collar needs GPS services and cellular data to create, edit, and use wireless dog fences. Pack Membership Plans start at $9.99 per month and you select one after purchase.
• Perfect fit: For dogs big or small, the tailoring system lets you custom fit the collar to your dog’s exact neck size, all the way from 8 inches to 30.5 inches.
