Halo Collar vs SpotOn: Which GPS Dog Fence Fits Your Yard?
Heads up: this post contains affiliate links. If you buy through them we may earn a commission, at no extra cost to you. Learn more.
Halo and SpotOn are the two names that come up most when people look for a wireless GPS dog fence, and they're built for different yards. The short version: Halo suits smaller yards and owners who want several saved fences, but it needs a monthly membership. SpotOn is built for larger properties and works without a plan, but it costs more up front and the collar is bigger.
Below we compare them on the things that actually decide it: subscription, yard size, multiple fences, collar size, battery and training. We also cover when a GPS tracker like Fi or Tractive makes more sense than a fence. Specs come from each brand's listing and published details; we don't list prices because they change, so check the current price on Amazon. For the full lineup of GPS fences and trackers, see our GPS dog fence guide.
The collars compared
1Halo Collar 5: best for smaller yards and multiple fences
Halo is the best-known GPS fence collar. You create fences in the app and Halo says the collar can store an unlimited number of them, which helps if you want one fence at home, another at a relative's house and one at a cabin. Halo's own specs list a minimum fence size of about 30 by 30 feet, so it can work on smaller suburban lots that are too tight for some GPS fences. The collar connects over LTE, Wi-Fi and Bluetooth, Halo rates the battery at up to 48 hours, and the app includes a structured training program with videos.
The big trade-off: a Halo membership is required. The collar isn't a one-time purchase, so add the monthly plan to the cost before you decide. Reviews on Amazon are mixed, so read recent ones.
Best for: smaller yards, owners who want several saved fences, and people who like a guided training program.
Skip it if: you don't want a monthly fee for the fence to work.
2SpotOn Nova: best for bigger properties and no required plan
SpotOn's pitch is accuracy over larger properties and no subscription required for the fence itself. You draw the boundary in the app, and the fence keeps working without a plan; SpotOn sells an optional cellular plan that adds live tracking and alerts. SpotOn's listing describes dual-band GPS built for dense trees and hilly ground, and it supports keep-out zones.
The trade-offs: the upfront cost is higher, the collar is heavier than Halo's (SpotOn says it's for dogs 15 lbs and up, with neck sizes from 10 to 26 inches), and SpotOn is aimed at properties of roughly a third of an acre and up, so it isn't the pick for a small lot. Battery life is shorter than Halo's, so plan on charging it often.
Best for: rural and large suburban properties, wooded or hilly land, and owners who'd rather pay once than monthly.
Skip it if: your yard is small, or your dog is under about 15 lbs.
3Fi Series 3+: a tracker, not a fence
If your dog mostly stays home and you mainly want to know where they are when they slip out, a GPS tracker may be all you need. Fi tracks location and activity and alerts you when your dog leaves a safe zone, but it doesn't give boundary corrections or keep your dog in. A Fi membership is required for GPS tracking.
Best for: escape artists in fenced yards, and owners who want a lighter everyday collar with tracking.
Skip it if: you need the collar to actually keep your dog inside a boundary.
4Tractive GPS tracker: the budget escape alert
Tractive clips onto your dog's existing collar and gives live tracking and virtual fence alerts on your phone. Like Fi, it alerts you rather than keeping your dog in, and it needs a subscription. It's the lowest-cost way to get GPS on a dog.
Best for: a backup for dogs that occasionally bolt, travel, hikes.
Skip it if: you need containment. Look at Halo or SpotOn above.

How to choose
- Measure your yard first. If it's under about a third of an acre, Halo is the realistic option. On larger or wooded land, SpotOn's focus on accuracy is the reason to pay more.
- Do the two-year math. Add Halo's monthly membership to the collar cost and compare it with SpotOn's higher one-time cost (plus its optional plan if you want tracking).
- Check your cell coverage. Both rely on cellular service for app features. Weak coverage at the edges of your property is worth knowing about before you buy.
- Think about your dog. Small dogs may find SpotOn's collar too big. Dogs that ignore recall need serious training with any GPS fence.
- Keep a backup. A GPS fence is a training tool, not a wall. Many owners pair one with a tracker tag for peace of mind, and keep dogs leashed near busy roads.
Frequently asked questions
Does Halo Collar need a subscription?
Yes. Halo lists the collar as subscription required, and the membership is what runs the fences, tracking and app features. Factor the monthly plan into the total cost over two or three years.
Does SpotOn need a subscription?
Not for the fence. SpotOn says the GPS fence works without a plan, and an optional cellular plan adds live tracking and escape alerts.
Which is better for a small yard, Halo or SpotOn?
Halo. Halo lists a minimum fence of about 30 by 30 feet, while SpotOn is designed for properties of roughly a third of an acre and up. Very small yards are hard for any GPS fence, because GPS accuracy is a few feet at best, so leave a buffer from roads.
Can a GPS collar replace a real fence?
Not completely. GPS fences don't stop other animals or people from coming in, and a determined dog can still run through a boundary. Both brands recommend several weeks of training with flags and a leash, and they work best for dogs that already have solid recall. Ask your vet or a trainer whether boundary corrections suit your dog.
