Why is SpotOn the Most Accurate GPS Dog Fence?


As the original GPS dog fence, SpotOn has been testing, learning and optimizing dog containment since January 2019. Our multiple patents power SpotOn’s True Location™ technology which provides the most accurate GPS dog fence. Unlike other systems, this AI-enhanced GPS shows your dog’s true location, rather than relying on satellite data alone.

With SpotOn GPS Fence, your pup can roam free in all locations without you having to worry about checking for a good GPS signal before training or letting him loose — or having the boundaries fail once outside.

How does True Location™ technology make SpotOn the most accurate and reliable fence?

Access to more constellations, combined with the GPS antenna’s quality and location, affects how many satellites can be connected at once. Better connection to more satellites means boundary accuracy and static correction are not impacted by cloudy weather or tree coverage. Your dog can freely move within the boundaries you set without being falsely corrected or not corrected at all. 

Constant communication with more Satellites 

SpotOn taps into 128 satellites across four global satellite systems (GPS, GLONASS, Galileo & BeiDou).


This system, combined with SpotOn’s intelligent adjustment algorithms, pinpoint your dog’s location to typically within three feet and ignores GPS signals partially blocked by buildings or trees. 


GPS works best when it has an unobstructed view of the satellites. SpotOn’s antenna is set on the back of your dog’s neck where his body can’t block it, to maintain more accurate boundaries and a better overall connection. 


The SpotOn collar uses GPS alone to create, activate and maintain fences. GPS is always available, everywhere (even in remote areas) so the signal will not get spotty.


It auto-corrects your dog’s location, so his boundaries and his position are more accurate.


SpotOn automatically adjusts to increase GPS sensitivity when the signal is inconsistent. This means that your fence boundaries are more reliable.


It never issues a correction to a dog that has left his boundary and is on his way home.

Provides 1,500 fence posts for a more precise and CUSTOMIZABLE FENCE 

More posts means more precise boundaries, and the ability to customize your fences to your property (and across water or tricky terrain). Plus, you can add Keep Out Zones to create off-limits areas within your fence.

How did we create the most accurate GPS dog fence?

SpotOn gathered a team of engineers that created GPS devices for the US military and applied that knowledge to invent the first GPS containment system for dogs. We hold multiple patents, have been in the market since January 2019, and have thousands of dogs who rely on SpotOn. We have tested our GPS fence system with thousands of dogs, including independent livestock guardian dogs, rough and tumble farm dogs, and wandering suburban dogs. We’ve worked through challenges with durability, technology, and bugs to identify and resolve problems to deliver the best GPS dog containment experience.

But how do real-world dog owners feel?

An advanced, innovative, high-tech product is only as good as the user's experience. Technology can be intimidating for some and SpotOn's goal is to make its virtual fence and collar as easy-to-use as possible. 

Sadie Cornelius, a dog parent to a Cavalier King Charles Spaniel and contributor at LoveYourDog.com, was impressed with how easy it was to get started with SpotOn.

“Overall the collar’s responsiveness and user experience are both excellent in my experience. After completing the detailed training program, I feel positive he’ll get the hang of the collar in no time, and am confident in the technology behind this product. I walked the perimeter of the park going around obstacles like benches and trees as I watched the app draw the fence in real-time. I was impressed at how detailed the fence line was, and I was eager to test the boundaries. It’s amazing how accurate the invisible fence lines were. When getting close to the “edge,” it makes a loud beep. As you get closer to the boundary, there is a two-tone alert. And if you cross the boundary, the collar vibrates.”

Getting Started with SpotOn

SpotOn Fence functions for 1/2 acre to 1000's of acres, so it is a great solution for large acreage. With our easy-to-use app, you can create virtual fences any size, any shape, and nearly anywhere!
