The Most Reliable GPS Fence for Dogs 

At SpotOn, our technology sets us apart. Containing a dog within a virtual fence is only effective with the ability to remove GPS’s inherent limitations such as drift, multi-path signals, and interference. SpotOn’s patented True Location™ technology does this by gathering the GPS data from motion sensors in the collar that track your dog’s direction, speed, and acceleration and applying patented AI to position your dog’s true location with more accuracy than other GPS fences.

We pair our True Location™ technology, with the best GPS hardware. SpotOn's dedicated GPS antenna is positioned at the back of the dog's neck where it has the best view of the satellites. This highly-sensitive antenna harnesses the power of four global satellite systems simultaneously (other pet tech can access only one at a time), to pinpoint and predict your dog’s true location and provide more accuracy in the GPS fence boundary, more freedom for your dog, and more peace of mind for you, so you can leave your dog to go about his business, while you go about your day.

Another bonus, SpotOn's GPS dog fence runs completely independently, is always on, and doesn’t require a subscription or additional fee.


A completely self-contained GPS fencing system SpotOn does not need wires, base station, or power source. Unlike other GPS fences, SpotOn never requires GPS calibration and never needs to recalibrate, so your fence boundary will remain consistent over time, and it will be ready to go whenever you need to use it! 


SpotOn connects to 25-30 satellites at any one time - and can pinpoint your dog to within 3 feet of his location. Simultaneously receiving and tracking signals from four navigation satellite constellations including GPS (US), Galileo (European Union), Glonass (Russia), and BeiDou (China).  


SpotOn’s GPS fencing for dogs uses a best-in-class, dual-feed collar antenna, optimally positioned on the back of the dog’s neck so it has a clear view of the sky and filters inferior GPS signals partially blocked by buildings or trees.


Our patented containment algorithm never issues a warning or a correction to a dog returning home. SpotOn's GPS dog fence technology interprets the direction of travel and only issue warnings and corrections to a dog attempting to breach the boundary.


Patented indoor detection. SpotOn’s smart technology can recognize if your dog is inside or outside. So even if your fence boundary is close to your house, your dog will never get warnings or corrections while indoors.


SpotOn’s Forest Mode improves GPS performance under dense leaf cover from trees, brush, or bushes. Sometimes, if your dog is under heavy leaf cover, SpotOn may think your pup is indoors and suspend warnings and corrections. Activating forest mode will disable indoor detection.
