Best Dog GPS Trackers Compared on Maker Specs (2026)
Three cellular GPS trackers for dogs, compared on the numbers each maker publishes. We have not tested these trackers ourselves.
We may earn a commission when you buy through links on this page, at no extra cost to you. This does not change which products we cover. How we make money.
A GPS tracker tells you where your dog is when it slips the leash, using its own cellular link instead of a nearby phone. The Tractive DOG 6 is the pick for most dogs, the Fi Series 3+ lasts longest between charges, and the 16 g Fi Mini suits small dogs and cats.

The picks
★Best for most dogs
TractiveDOG 6
Best for: Most dogs over 8.8 lb, on any collar
A 39 g clip-on LTE tracker for dogs over 8.8 lb with GPS, GLONASS and Galileo, IP68 rating and up to 14 days of battery with Power Saving Zones.
What we like
- Clips onto collars up to 1.1 in wide
- Three satellite systems
- USB-C charging
Watch out for
- Shortest battery of the three without Power Saving Zones
- Needs a Tractive subscription
The DOG 6 clips onto a collar up to 1.1 in wide, so your dog keeps its own collar. It weighs 39 g, uses GPS, GLONASS and Galileo, and connects over LTE, with Wi-Fi and Bluetooth for home detection. Tractive quotes up to 14 days of battery with Power Saving Zones, which pause GPS when the tracker sees your home Wi-Fi, and up to 6 days without them. LIVE mode updates every 2 to 3 seconds and uses more battery. It charges by USB-C in about 2 hours, per the manual.
★Longest battery
FiSeries 3+
Best for: Long battery life and a collar that stays on
A 47 g tracker built into a collar band, rated IP68/IP66K, with a stainless steel body, a night light and up to 3 months of battery.
What we like
- Longest listed battery life
- Stainless steel body
- Base station included
Watch out for
- Heaviest of the three
- Lost Mode drains the battery in about 2 days
Fi builds the Series 3+ into the collar band, with a stainless steel body that Fi says resists chewing. Fi gives a range for battery life: up to 3 months for a dog that stays home or takes short walks, 4 to 6 weeks for a dog that goes in and out of the yard, and up to 2 weeks for a dog that roams outdoors. Lost Mode tracks every few seconds and lasts about 2 days. It ships with a Fi Base for charging and home detection.
★Smallest
FiMini
Best for: Puppies, small dogs and cats
A 16 g clip-on tracker Fi recommends for puppies, small dogs and cats, rated IP68 and charged by USB-C.
What we like
- Lightest here at 16 g
- Attaches to most collars and harnesses
Watch out for
- Fi lists two different battery figures
- No night light
At 16 g, the Fi Mini is less than half the weight of the other two, and it attaches to most collars and harnesses. Fi recommends it for puppies, small dogs and cats. One catch: Fi’s battery page says up to 3 weeks, while its comparison chart says up to 2 months. Plan around the lower figure.
How to choose
- Check coverage. Each tracker runs on one network: Tractive works across several, Fi Series 3+ on AT&T and Fi Mini on Verizon. Check the map for where you walk.
- Weigh it against your dog. Tractive sets a floor of 8.8 lb for the DOG 6.
- Count the subscription. The tracker price is only part of the cost.
- Keep the microchip and tag. A tracker adds to ID; it does not replace it. See the AVMA on microchipping.
Frequently asked questions
Do dog GPS trackers need a subscription?
Yes, all three here. Tractive says every tracker needs an active Tractive subscription, and Fi sells its collars with a Fi membership. Check current plan prices on each maker site.
Is an Apple AirTag a GPS tracker?
No. An AirTag uses Bluetooth and nearby Apple devices, not GPS or its own cellular link. Fi notes that Apple does not recommend AirTags for tracking living things.
Which tracker suits a small dog?
Tractive lists the DOG 6 for dogs above 8.8 lb. Fi recommends the 16 g Fi Mini for puppies, small dogs and cats.
Does a GPS tracker replace a microchip?
No. A tracker can fall off or run out of battery. The AVMA says a microchip gives permanent ID, that microchipped pets should also wear a collar with current ID tags, and that you must keep your contact details current in the chip registry.
