Quick answer: The Tractive Dog 6 Mini is the best GPS tracker for small dogs for most owners, because it is built for dogs from 3 to 18 lbs and weighs 32 g. If you want the lightest option, the Fi Mini weighs just 16 g and the Pawfit Lite weighs less than 18 g. For the longest battery life, pick the Life360 Pet GPS Tracker.
Small dogs slip through fence gaps and dart out of open doors, but many GPS trackers are sized for bigger dogs and feel bulky on a tiny neck.
I compared GPS trackers on Amazon by weight, recommended dog size, battery life, alerts, and owner feedback. I have not tested these trackers myself; my picks are based on manufacturer specifications and verified owner reviews.

How to Choose a GPS Tracker for a Small Dog
Weight and size
Check the brand’s recommended dog size first. For toy breeds, the Fi Mini and Pawfit Lite are the lightest units here.
Collar fit
Clip-on trackers work with your dog’s existing collar; just make sure the clip fits its width.
Battery life
If you often forget to charge, the Life360 Pet and standard Tractive list up to 14 days.
Subscription
Every tracker here uses cellular data, so each needs a plan after any included trial. Factor in that ongoing cost.
Alerts and extras
Escape alerts matter most for dogs that bolt; activity insights are a bonus.

Final Thoughts
The Tractive Dog 6 Mini is my top pick because it is built for dogs from 3 to 18 lbs and keeps Tractive’s fast live tracking. Choose the Fi Mini or Pawfit Lite if every gram counts, the Life360 Pet for the longest battery life, or the standard Tractive Smart Dog for a sturdier small dog over 8 lbs.
Note: Health and activity features on pet trackers are informational, not a diagnosis. If you notice changes in your dog’s breathing, sleep, or energy, talk to your vet.
