Start with where your dog goes
A dog tracker needs to fit your dog, communicate in the places you visit, and have a service plan you will keep active. Those checks matter more than an “unlimited range” headline.
Selection method: We compared published specifications and the linked listings on September 15, 2026. We have not conducted a comparative field test or measured an accuracy or alert-speed winner.
For the detailed table, see Fi vs AirTag vs Tractive.
1. Verify remote coverage
GPS finds a location; a communication network delivers it to your phone. Check coverage at home, the dog sitter's address, and your usual walks.
Tractive says its tracker needs satellite access and cellular coverage to send locations. See its tracking requirements. Fi Series 3+ uses AT&T LTE-M.
If your route has no supported signal, pause this purchase decision. A map showing the dog's last location does not demonstrate a working live connection.
2. Choose the format that fits
Fi Series 3+: integrated collar
The linked Blue Large bundle includes six months of membership.
Choose it when: You prefer an integrated collar and its sizing works for your dog.
Check first: Measure your dog and read the renewal offer. Included service is a finite period. Compare the amount due at renewal with the total you can maintain, using Fi's billing information and your actual offer.

Tractive DOG 6: collar attachment
The linked black DOG 6 attaches to a collar. Manufacturer guidance specifies dogs from 9 lb, with collar widths up to 1.1 inches. Weight alone cannot establish comfort on a small dog.
Choose it when: You want to keep a suitable existing collar and have confirmed local coverage.
Check first: Subscription costs are separate. Verify country coverage, billing term, and features requiring Premium in the DOG 6 specifications and current plans.

AirTag: a different purchase
The linked first-generation AirTag 4-pack is an item-tracking product. Apple introduced a newer generation in 2026, so check generation as well as pack size.
Apple says AirTag is designed for objects, not pets. Its network depends on nearby participating devices, without a promised continuous location feed. We include it to explain a common comparison, not as our budget dog-GPS recommendation. Apple's intended-use statement.

3. Budget for the whole purchase
| Before checkout | What to record |
|---|---|
| Hardware | Exact model, size, mount and accessories |
| Service | Included months and activation requirements |
| Billing | Upfront charge, renewal amount and interval |
| Travel | Supported destinations and required plan upgrades |
| Returns | Hardware return window and separate subscription terms |
A two-year prepaid offer can show a low monthly equivalent while charging the entire term at once. Six included months do not cover a full year. Use actual checkout totals over a matching period.
4. Plan for charging
Manufacturer maximums apply under particular conditions. Fi's three-month estimate describes low activity; its other usage estimates are shorter. DOG 6's up-to-14-day figure uses Power Saving Zones; without them, its estimate is up to six days. These are not measured continuous-recovery runtimes from our testing. See Fi battery conditions and Tractive battery conditions.
Decide where charging fits your routine and check the battery before outings.
5. Test while your dog is on a leash
- Secure the attachment according to its instructions.
- Enable the app's required permissions and notifications.
- Walk through the safe-zone boundary together and check the notification.
- Check the location timestamp and connection status.
- Make sure another caregiver knows the setup if your plan supports sharing.
A tracker does not replace properly fitted equipment. See our escape-resistant harness guide and walking essentials checklist.
