The #1 Rated GPS Dog Fence

SpotOn has been independently proven to be the most accurate GPS smart fence.

SpotOn is accurate to three feet under open sky and ten feet under heavy tree cover or near buildings. As a point of comparison GPS-enabled smartphones are typically accurate only to within 16 feet under open sky and greater than 16 feet near buildings, bridges, and under trees.  

The accuracy of all GPS systems depends upon several factors including the quality of the GPS receiver and antenna, the number of satellites detected, and how much of the sky is in clear view from the ground. GPS satellites are continuously moving across the sky, above and below the horizon. The more satellites a GPS system can detect the greater the accuracy. GPS systems are more accurate in a large flat open field where there is a clear view of the sky.  Areas with large objects like buildings, hills, and heavy tree cover can reflect GPS signals, reducing accuracy.

SpotOn has access to a network of 128 satellites across four satellite navigation constellations including GPS (US), Galileo (European Union), Glonass (Russia), and BeiDou (China) and can simultaneously receive and track signals from up to 30 satellites at one time. SpotOn uses a dual feed antenna that is designed to detect and ignore reflected signals. SpotOn includes Forest Mode which improves accuracy in areas with heavy tree cover. Click here for more information on the tech that powers SpotOn.

Since the entire SpotOn system is self-contained in the collar, each dog requires their own collar and their own (optional) cellular subscription. You can share fences between collars and manage multiple collars through the App.

We offer an automatic discount per collar for multi-collar purchases: $100 off per collar, as of August 2024. Offer subject to change. Cannot be combined with any other offers or sitewide sales (deepest discount will apply).

SpotOn comes in three sizes to fit most dogs fifteen pounds or more and with neck sizes between 10” and 26”. It’s important to measure your dog’s neck size prior to ordering. How to measure.

Measure your dog’s neck just above where his regular collar sits. Make sure you can fit one or two fingers between the measuring tape and your dog’s neck.

You’ll know you have ordered the right size, when the SpotOn dog collar fits snuggly and the antenna sits on the back of your dog’s neck. This ensures the best possible GPS connectionーthe more sky the antenna sees, the more satellites it can connect to, the more precise your boundary lines will be! 

If your dog is a puppy, we recommend waiting to purchase until she’s about six months old (or when you have a good idea of her adult size).

Yes!

Unlike your phone, SpotOn Fence can access GPS without a cellular connection. GPS is available anywhere you can see the sky, and it’s free. Just like your old Garmin® navigation system for your car!

SpotOn uses GPS to create, manage and activate fences or contain your dog. Thousands of customers use SpotOn off-grid, in remote areas with no cellular service.

With an optional cellular subscription, you can unlock some additional features. Cellular enables the SpotOn Fence to communicate with your phone over long distances. With cellular, you can:

• See your dog's location at any time, which is useful if your fence is large.
• Receive notifications if your collar battery is low or your dog escapes.
• Track your dog if he escapes.
  

You purchase a cellular subscription for your SpotOn Fence through us. It is not part of your phone bill. We offer several flexible plans and you can cancel anytime.

To give your dog enough space to roam without frequent feedback, we recommend you have ½ acre or more. The fence should be at least 80 feet wide at its narrowest point. Because your dog will hear tones 10 feet inside the boundary, if your fence is too narrow at any point, your dog will not be able to move freely without constantly hearing tones. 

Additionally, when planning your fence, account for GPS drift ーtypically between 3 to 10 feet near tall structures or heavy forest. It is important to include a 15-foot buffer zone between the boundary and any unsafe area, like a major roadway.
