Underground Dog Fences Built for Freedom
Boundary Plus® technology creates a custom underground dog fence for your yard, giving your dog more freedom to roam safely.

Our Underground Dog Fence Gives Your Pet More Room to Roam
Up to 30% more play area over other leading pet fences. The Boundary Plus® system creates an ultra-precise boundary line giving your pet more space and is ideal for unique shaped, complex or small lots. The system also keeps your pet safer, longer with our Power Cap® Batteries that run for up to 3 months. Our complete home system includes Indoor and Outdoor Shields® units to keep pets out of off-limit areas like trash or furniture, while still allowing freedom to roam.
Our system uses patented Correction-Free Return technology. If your pet crosses a boundary, they will not receive a correction when returning home.
Complete Your Underground Fence System
Expand your Boundary Plus® system into a whole-home solution. Customize your pet's boundaries inside and out with these compatible add-ons:
Protect Specific Areas: Use Indoor and Outdoor Shields® units to keep pets away from off-limit spots like furniture, landscaping, or trash bins.
Automate Entry: Install the Doorman™ automatic pet door, which opens only for your pet. It keeps wildlife out and lets you set curfew schedules.
What Sets Our Boundary® Plus Underground Dog Fence Technology Apart From the Others?
Three Personalized Training Sessions
Included with the purchase of your system and its installation, your pets receive three hands-on training sessions with our certified trainers at no additional cost! This ensures your pet gains an understanding and confidence in their new boundaries.
Customizable Indoor and Outdoor Pet Fence Systems
Protect your home without gates or closed doors - from the living room to the backyard, your pet stays safe wherever they roam.
Different Rules For Different Pets™
Specific rules can be applied on both indoor and outdoor fences to give your whole pack more freedom. Keep your dog out of the trash and the rose bush and your cat in the house, but off the counter.
Freedom to Return
If your pet crosses the underground fence, our patented technology detects the time since the boundary was crossed and the return of you pet. So they are always free to return home safe and correction free.
