A GPS dog tracker needs enough power and connectivity to remain useful when your dog is missing. Compare the exact model’s weight, dimensions, coverage and battery conditions—not only the longest runtime printed on its product page.
Will I have to charge it every few days?
Possibly, but not always. As checked September 24, 2026, Tractive’s battery guide lists its DOG 6 at up to 14 days with a Power Saving Zone and up to 6 days without one. Its DOG 6 XL is listed at up to 6 weeks with that feature and up to 20 days without it. These are manufacturer estimates, not our test results.
The same guide explains that live tracking, signal conditions and cold weather can affect consumption. A maximum runtime under favourable conditions is not a guarantee for a long search. Keep enough charge for unexpected escapes and learn how your device warns you when power is low.
Plan for time off the collar
Ask how the device charges and whether it must be removed. If it is charging at home, it cannot report the location of a dog that leaves without it. Keep visible identification attached during that gap. A QR tag needs no charging, but it also cannot tell you where an unseen dog is.
Are GPS trackers heavy?
“Heavy” depends on the device, attachment and dog. For one concrete example, Tractive lists the DOG 6 at 1.4 oz (about 40 g) and recommends it for dogs above 8.8 lb (4 kg). Other models differ. Check the complete attachment weight and how it sits on your dog’s collar.
We have not yet published measured weights for our stainless steel tags, so we do not claim they weigh less than every tracker. Compare the real items and hardware, especially for a small dog. Ask the manufacturer about fit if the device swings, rubs or interferes with normal movement.
GPS reception and sending an update are different
A cellular tracker must determine a location and send it through a supported network. Check the manufacturer’s coverage for the places you actually walk or travel, including rural areas. The DOG 6 product documentation describes GPS/LTE connectivity and a subscription; do not assume every GPS device uses the same network or payment model.
A checklist before you buy
- Check normal-use and live-tracking battery expectations for the exact model.
- Check size and weight including its collar mount.
- Confirm coverage, phone compatibility and subscription terms.
- Understand low-battery warnings and time needed to charge.
- Keep readable identification and microchip records current.
Read the GPS, microchip and QR comparison to decide which combination covers your needs. We sell QR tags, and have not independently tested the trackers discussed here.
