FitBark
FitBark GPS 2nd Gen matches Fi Mini at 16 g and supports on-board GPS, multi-network LTE-M, Wi-Fi, cell-tower assistance, and Bluetooth. It works for pets from 5 lb in four officially supported countries and has flexible long-term subscription pricing, but the battery claims vary dramatically by mode: the six-month figure is Bluetooth-only, while continuous live GPS is rated up to six hours.
Petloc8
Petloc8 Mini weighs 25 g including its silicone attachment and uses GPS, 4G LTE Cat 1, Wi-Fi, Bluetooth, and an embedded roaming SIM. Five-second live updates, service-included purchase options, an eight-image gallery, and a product-level rating make it well evidenced, but it is officially intended for pets above 4 kg and the product page contains conflicting two-week versus seven-day battery language; the Mini comparison and FAQ consistently support seven days.
PAJ GPS
PAJ's PET Finder 4G Mini is a true GPS tracker with its own European 4G SIM, Bluetooth-assisted indoor power saving, a 33.1 g body, and a 3 kg minimum dog weight. Its purchase includes more than two years of service and the official page provides unusually complete technical and media evidence, but it is the heaviest tracker in this lightweight ranking, continuous tracking lasts only one to two days, and it is not designed for U.S. cellular use.
Molly&Cody
Tracker T1 is a roughly 25 g pet tracker that officially lists GPS, Wi-Fi, LBS, Bluetooth, and—on its technical page—cellular positioning. Its standard battery claim is up to six days and its official gallery and video are complete, but Molly&Cody does not disclose the cellular generation, radio bands, partner carriers, supported countries, minimum pet weight, or full subscription matrix. It therefore ranks only as a conditional option after buyers confirm local network support directly with the brand.
Tractive
Tractive's CAT 6 Mini combines GPS, GLONASS, and Galileo positioning with its own LTE Cat 1bis connection, Wi-Fi, and Bluetooth in a 32 g collar-integrated design. It offers the most complete mix here of documented worldwide operation, live tracking, health features, safety-release construction, and mature public evidence, but it still requires cellular coverage and a paid plan, and its seven-day claim assumes use of Power Saving Zones.
Tractive
A 1.4-oz clip-on GPS tracker for dogs over 8.8 lb, with two-to-three-second Live Tracking updates, IP68 protection, virtual fences, light and sound tools, and health trend monitoring. The advertised battery reaches 14 days only with Power Saving Zones; remote tracking requires a paid plan and compatible cellular coverage.
