A GPS pet tracker turns "my dog got out" from hours of searching into a map you can follow. A small cellular unit on the collar reports your pet's location to your phone, alerts you the moment they leave a safe zone, and lets you follow them live until you catch up.
An update for Whistle owners: Whistle, this page's former top pick, was bought by Tractive, and its service ended on August 31, 2025. Whistle trackers no longer work. Tractive offered owners a free replacement tracker with a plan. If you still have a Whistle on your dog's collar, it isn't tracking anything.

The most important distinction is cellular GPS versus Bluetooth. Cellular trackers (Tractive, Fi, Life360) use GPS to find your pet and a mobile network to report it, so they work anywhere with cell coverage, however far away your pet is. Bluetooth tags like the AirTag are not GPS trackers: they only show up when a nearby iPhone passes within range, so they can't follow a dog running through woods or open fields.
Every cellular tracker needs a paid plan, so compare the yearly cost, not just the device. Tractive's prepaid plans run $108–$120 for one year, or about $5–$7 a month on longer terms. Fi's membership is $189 a year, plus a $20 activation fee. Life360 Pet includes its first 12 months, then auto-renews. All of them depend on cell coverage, and owners in rural areas report patchy tracking on every brand, so check coverage where your dog actually roams.
The Fi Series 3+ is a full collar rather than a clip-on tracker, with the GPS built in. Fi rates the battery at up to 3 months per charge, by far the longest here, and it charges on an included base. It uses the LTE-M network, has a Lost Mode that switches to rapid live updates, an IP68 waterproof rating and a built-in LED light, and comes in sizes XS to XL. The catch is cost: membership is $189 a year (or $99 for 6 months), plus a $20 activation fee. Like every cellular tracker, owners in rural areas report weak tracking.
Life360 Pet tracks over GPS, LTE and Bluetooth with virtual fences and escape alerts, and Life360 rates the battery at up to 14 days. Its draw is the included first year of service and that it shows up in the Life360 app many families already use to share their own locations. After 12 months the plan auto-renews.

Tractive's prepaid plans run $108–$120 for a year, or about $5–$7 a month on longer terms. Fi charges $189 a year plus a $20 activation fee. Life360 Pet includes its first 12 months. Bluetooth tags like the AirTag need no plan, but they aren't GPS trackers.
No. Tractive bought Whistle, and Whistle's service ended on August 31, 2025, so Whistle devices and the app stopped working. Tractive offered owners a free replacement tracker with a plan.
Only for finding a dog nearby. An AirTag uses Bluetooth and shows up when an iPhone passes within range, so it can't follow a dog live or alert you when it leaves the yard. For an escape-prone dog, a cellular GPS tracker is the right tool.
Accuracy is best outdoors with a clear view of the sky, and worse indoors, under dense tree cover or among tall buildings. Small yards are the hard case: normal GPS drift can trigger false escape alerts, which is the most common complaint in owner reviews. Many owners draw the virtual fence a little larger than the property.
It varies with how often the tracker reports. Tractive and Life360 rate theirs at up to 14 days, and Fi rates the Series 3+ at up to 3 months. Frequent live tracking drains any of them much faster than these maximums.
