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.

Series 3+ Smart Dog Collar is worth considering if best integrated collar and home battery is your priority in gps dog trackers. Check fit, current price, and retailer availability before buying.
Skip it if a membership with at least a six-month commitment is required, and the current u.s. plan also has an activation fee is a dealbreaker, or if your pet needs a different fit, size range, or retailer return policy.

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.
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.
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.
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.
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.
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.
