DOG 6 GPS & Health Tracker is a strong best overall pick for shoppers comparing gps & health tracker options in gps dog trackers. Key strengths noted in the product information are: Live Tracking can refresh every two to three seconds across supported cellular networks; Lightweight 1.4-oz body, IP68 protection, and a clip for collars up to 1.1 in wide. Buyers should still check sizing, current price, and retailer availability before ordering.
DOG 6 GPS & Health Tracker is worth considering if best overall is your priority in gps dog trackers. Check fit, current price, and retailer availability before buying.
Skip it if a paid plan is mandatory, and location delivery stops where compatible cellular service is unavailable is a dealbreaker, or if your pet needs a different fit, size range, or retailer return policy.
Compare related options, then check current details with the retailer.

Fi
An integrated GPS/LTE-M dog collar with a night light, activity and AI behavior trends, and exceptionally long battery claims when the dog stays near its Fi Base. Outdoor-heavy use is shorter, an active membership is required, and Series 3+ has no satellite link for areas without AT&T LTE-M coverage.
Petcube
A low-cost 29 g LTE-M tracker with live location, Lost Dog mode, virtual fences, activity history, a light, and a buzzer. Its 30-day battery claim requires a Wi-Fi Power Save Zone, while remote tracking needs a paid plan and compatible LTE coverage that Petcube does not map publicly on the product page.

Pawfit
A 0.95-oz satellite-GPS and 4G-LTE tracker for dogs and cats over 7.7 lb. Find mode can update every five seconds, while IP68 protection, safety zones, light, sound, and an 18-month warranty support everyday outings; a paid plan and adequate GPS and cellular coverage remain mandatory.

SATELLAI
A newer 47 g LTE tracker with two-to-three-second Live Tracking, five-GNSS positioning, virtual boundaries, two-way audio, a safety light, and IP68 protection. Its 4.5-day maximum is shorter than several rivals, a paid plan is required, and only 19 brand-site reviews were available when checked.


Fi
Fi Mini weighs only 16 g and is explicitly positioned for puppies, small dogs, and cats, with real-time GPS, Verizon LTE-M, IP68 protection, and flexible collar or harness attachments. Its latest comparison page advertises up to six weeks, or up to three months with a Fi Base, but those are conditional maximums; service is membership-based and the public brand review profile is unusually polarized.

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.
