Top 6 Things to Know Before Getting Your SpotOn Fence


Wondering if SpotOn GPS dog fence is right for you? We put together a list of our most commonly asked questions and answered them below! We know that SpotOn Fence is an investment for you and your family, so we've got you covered even after you purchase. We offer a 90-day money-back guarantee so you can see if SpotOn GPS Fence is a good solution for your pup and your property!  

Will SpotOn work for my property?

You can use our system on as little as half an acre and there is no maximum limit​. GPS accuracy can vary up to 10 feet, so you also need 15 feet from the outside of your boundary to any unsafe environments. It's important to plan your fence to be at least 80 feet wide at its narrowest point. This will ensure your pup has plenty of room to roam without hearing the tones!

Can I use SpotOn to get around obstacles or make fences through water?

Of course! All you need is your smartphone and you can draw your fences using the SpotOn app to your liking. If you need to be more specificy with your boundary, you may walk your fence and simply press the “Pause” button when you encounter the obstacle. Then, navigate to spot where you'd like the fence to continue the fence line (when the terrain allows) and press “Resume” to continue your path. SpotOn GPS dog fence will automatically “snap” a straight line between the two points. 

Here are a few scenarios where the pause feature is a sneaker-saver: 

  • Through water- Does your pup love to swim? Use Pause to give him access to the beach, snap a line through a pond, lake or along a river!
  • Thick brush- Use the pause feature to snap a straight line over any bushes or rocky patches that crosses the border of your fence.  
  • Rough terrain- Do you have a swamp, muddy patch, or maybe even a slope that is too slippery to brave? Have no fear, the Pause feature is here!
  • Large fences- Your arm won't get tired from facing the collar’s antenna to the sky! Give your arm a break and hop in your ATV, truck, or however you want to get to your second fence post with this cool feature! Just click Resume once you get there and it will snap a straight line.
  • Through a structure- Only want to give your pup access to your backyard? Use Pause to snap a line through your home, shed or barn.


I have a lot of trees in my yard, will SpotOn work?

Yes! Unlike other systems out there, SpotOn GPS Fence has a Forest Mode that makes our SpotOn dog collar effective in the woods. If you have dense tree coverage or are worried about your system working on a camping trip, simply enable Forest Mode for increased GPS sensitivity! Just note, because Forest Mode enhances the GPS sensitivity, think of it as outdoor only mode - keep these things in mind when using Forest Mode:

  • Remove the SpotOn's dog collar when your pup comes indoors to be sure he or she is not alerted.
  • Deactivate your fence when your pup comes indoors to avoid the risk of your dog receiving a false correction. Again, just to be sure! This can be done from the app.


Will SpotOn fit my dog?

SpotOn's dog collar fits dogs with neck sizes 10” or larger, usually about 25lbs and over. Our collars come in size Small for dogs with neck sizes 10"-14", Medium for dogs with neck sizes 12"-18" and size Large for neck sizes 19"-26". 

It is important to note that the collar size is set because the technology is built into the straps, so it can’t be adjusted outside of the set ranges. ​And it's important the collar fits properly so the GPS antenna sits at the top of the neck, facing upward to the sky. Using a flexible measuring tape or rope, 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​.

On average, a fully charged battery lasts up to 25 hours in normal containment mode and take from 1-2 hours to come to full charge. ​We recommend charging your SpotOn dog collar when the dog comes in for the night, much like you would a cell phone. 

It is important to know that your battery life can fluctuate based on your dog's activity level and your location. Tip! If you're eager to get the longest runtime possible, you can shut off tracking mode when you're not actively using it to increase your battery life. Rest assured that if your dog leaves the containment area, you will still get notifications to your phone and be able to quickly switch on tracking mode. 

Does SpotOn GPS dog fence require cell service to contain my dog?

No! The system works off of GPS technology and satellites in sky, so it does not need cellular service to create or maintain a fence for your dog. Additional features that allow the collar to communicate with your phone - escape notifications and tracking your pup - do require cell service. SpotOn's optional Boundary Boost subscription is optional and includes a 90-day free trial period.  Subscription plan options are: $9.95/month, $95.40/year and $142.80/2 years.
