Boundary Plus® Underground Dog Fence Has 3+ More Feet to Play

Unlike other underground dog fences, Boundary Plus® doesn’t take away 3–10 feet of yard space before the line — giving your pet more room to roam, even on 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® to keep pets out of off-limit areas like trash or furniture, while still allowing freedom to roam.

Doorman™, a programmable smart door that opens only for approved pets, on your schedule—keeping inside pets in and unwanted animals out, can also be added to complete your pet's suite.

With our patented technology, if your pet crosses the boundary, there’s no correction for coming back home—so they always feel safe returning.

What Sets Boundary® Plus Apart?

Three Personalized Training Sessions

Training for small and large dogs, (and cats too!) on indoor and outdoor barriers by certified, animal behavior-educated trainers builds confidence and help pets understand their space.

Indoor and Outdoor Pet Fence Solution

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 bed while 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
