What’s The Best GPS Dog Fence You Can Buy in 2024?

What’s the best GPS Dog Fence technology to keep your dog safe in your yard? SpotOn, Halo, and PetSafe all claim to be the best, and they’ll all set you back a decent chunk of change. So I’m sure you wanna get this right, especially if you want to protect your dog from a road or a pond that gets dangerously cold in the winter. This is your pup’s life we’re talking about here.

Let’s cut through the marketing fluff and see the best GPS dog collar fence whose GPS technology is truly built to excel—especially in those heavily-wooded and low-cell-signal areas. This is a tech-centric analysis. Plus, at the end of this article, I have one tip you can implement today to help your furry friend understand the boundaries of your yard with a wireless fence more effectively.

I’ve been testing these collars for the better part of a year and to this day SpotOn’s GPS tech is still the best from what I can tell. While the Halo 3 made a huge leap over the 2+, the design is still not quite at SpotOn’s level. The PetSafe Guardian fills a nice void in the market, but it’s not really trying to compete with SpotOn and Halo.

PetSafe Guardian

So, first up is the PetSafe Guardian. Coming in at around $600 as of writing, it’s the most accessible option if you don’t want to break the bank. But what does this price tag offer dog owners in terms of technology and reliability?

The Guardian doesn’t boast high-tech antennas or access to a wide array of satellite networks, which brings us to our first consideration: precision. Without the details on its GPS tech, we can’t assume it’s designed for a high level of accuracy. If you’re trying to keep your dog safe from hazards, this could easily be a concern. Plus, it’s the only collar of the three that requires a base station.

The Guardian only allows a dog owner to draw fences on a map, there’s no option for walking the perimeter. So you have to trust that the map image is consistent with reality—which isn’t always true to a high level of precision.

So, the PetSafe Guardian? It’s a basic option that gets the job done for a smaller price tag.


Next there’s the Halo 3. It’s about $700 at the time of writing, and there’s a mandatory subscription starting at about $6.

The Halo collar 3 takes pride in its active GPS antenna, which effectively trades higher accuracy at the cost of larger components and more battery drain compared to the Guardian.

Halo doesn’t specify a dual-feed antenna, though, which might raise some eyebrows in the tech junky crowd. The collar catches signals from the global satellite networks: GPS, GLONASS, Galileo, and BeiDou while using their proprietary AI to make sense of all the signals. It also picks up NavIC, which covers India, and QZSS, which consists of four satellites over Japan. So those aren’t really relevant for most dog lovers.

Halo mixes GPS with Bluetooth and cell signals, aiming for an all-around connected experience. This helps provide real-time reactivity on your phone, but it doesn’t beef up the GPS accuracy.

Halo gives you the option to draw virtual fences by walking the perimeter, but you have to drop them manually. You only have 20 fence posts to work with, so the level of customization is somewhat limited.

GPS dog fence reviewer Zach Lovatt explains Halo's additional features.

Additionally, the Halo app integrates what they call the Dog Park, Training modules, and an Activity Monitoring feature.

The Halo 3 is a step above the PetSafe Guardian with its active antenna and reception of all the global satellite networks. However, unless their marketing department is downplaying their design, it’s not quite best-in-show from a tech perspective.


This brings us to the SpotOn GPS Fence. It’s usually around $1300, but its discounted to about $1,000 as I’m writing—we’ll see if that sticks around. Then there’s an optional subscription starting at about $6/month, which unlocks some nice features on your phone. But the SpotOn works as a wireless dog fence without a subscription, unlike Halo.

What drives the higher price tag? It’s all in the tech. Boasting a dual-feed active antenna, SpotOn is a titan in GPS precision. The dual-feed antenna can maintain circular polarization—which, in simple terms, leads to superior GPS tracking that’s perfect to use when your dog escapes the set boundaries or just to check out their location at any given time.

SpotOn also picks up on all of the global networks, along with some regional networks. This wireless pet fence uses AI-powered GPS signal processing to ramp up that accuracy even more.

You can create virtual or invisible dog fences by walking the boundaries, and the collar will drop fence posts automatically every 5 feet, maxing out at 1,500 posts. Plus you can create GPS-based home zones and keep out zones to further enhance the functionality of your fence.

If you want the best technology and don’t mind splurging for your peace of mind and your dog’s safety, SpotOn GPS dog fence is the way to go—it’s honestly the best wireless dog fence or GPS fence I have ever tested.

Now, as promised, here’s the one tip you can implement today to help your pup understand wireless dog fences or the boundaries of your yard more effectively.

If your dog is generally well-behaved but may occasionally dash off after wild animals, neighboring pets, or whatever it may be—you can add visual markers along with the GPS boundaries.

Use simple flags or signs, especially near potential hazards like roads or ponds. These markers reinforce the GPS limits for your dog, making it easier for them to understand where they shouldn’t go even without a physical fence. It’s a great combo of high-tech and traditional methods, perfect for dogs that love a good chase.

Now, this has been tech-centric analysis and I’m sure you want to see these collars in action. See my in-depth reviews focusing on fence boundary tests as well as comparisons:
