The single most common misunderstanding in this category is that a GPS tracker replaces a microchip. It does not, and the distinction matters.
A microchip is permanent, cannot be removed or run out of battery, and identifies your dog to anyone who finds them — days, weeks or years later. It has no location function.
A GPS tracker shows you where your dog is right now, and it is attached to a collar that can come off.
They solve different problems, and a dog should have both.
Who genuinely benefits from a tracker
- Dogs with a history of bolting or escaping
- Dogs walked in large open country, moorland, forest or farmland
- Sighthounds and scent hounds, who can cover extraordinary distances in minutes
- Working dogs — gundogs, hunting dogs, farm dogs
- Deaf dogs, who cannot be recalled by voice
- Nervous rescue dogs in their first months
- Anyone who has already lost a dog once
For a well-recalled dog walked on a lead in a suburb, it is a nice-to-have rather than a necessity.
How they work, and the limitations
GPS gives location. A mobile network connection transmits that location to your phone — which is why most require a subscription.
The limitations follow directly:
- No mobile signal, no live tracking. In genuinely remote country, which is where you are most likely to lose a dog, coverage may be poor. Some devices store a track and upload when signal returns
- Battery life ranges from around two days to a couple of weeks depending on device and update frequency. A tracker with a flat battery is a paperweight
- Update interval. Cheap devices may update every few minutes; a dog running covers a long way in that time. Live mode drains battery fast
- Accuracy is typically several metres, which is fine outdoors and less useful in dense woodland
- Attachment. It is on a collar. A dog who slips the collar, or whose collar catches and releases, is untracked
Bluetooth tags
A different technology worth distinguishing.
Bluetooth tags have a short direct range and otherwise rely on a crowdsourced network — other people’s phones passing nearby and reporting the tag’s position.
Useful in dense urban areas with a lot of users. Close to useless in open countryside, where nobody is passing.
They are cheap, have long battery life, and no subscription. They are not a substitute for GPS if your dog goes missing on a hillside.
What to look for
- Battery life, realistically stated, and how quickly it drains in live mode
- Subscription cost — check the ongoing price, not just the device
- Network coverage in the areas you actually walk
- Update frequency in live mode
- Waterproofing. Properly rated, not “water resistant”
- Weight, particularly for small dogs
- Attachment security. A mount that will not come off
- Geofencing — an alert when the dog leaves a defined area, which is genuinely useful for escape artists
- Track history, which tells you where they went even after you find them
- Whether it works abroad, if you travel
Practical use
- Charge it on a schedule. Sunday night, every week. A tracker only helps if it has power
- Fit it to a well-fitting collar or harness, and check it regularly
- Use geofencing for the garden if your dog escapes
- Test it before you rely on it — walk somewhere, check the app updates
- Keep the dog’s ID tag on as well
What matters more
Honestly: the boring things.
The microchip, with current details. Rescue centres and vets routinely scan chips registered to old addresses and disconnected phone numbers. That is the single most common reason a found dog is not reunited with their owner.
Check yours today. Look up the number, log in, and confirm the phone number is one you answer.
An ID tag with a current phone number, worn at all times. It is a legal requirement in many places, and it is what lets a member of the public ring you within a minute of finding your dog.
A long line, for a dog whose recall is not reliable. Prevention beats retrieval.

The cheapest tracker is a dog who cannot leave. For a new rescue, an adolescent whose recall has collapsed, or a scent hound in open country, a long line prevents the problem a GPS unit only helps you solve afterwards.
A properly fitted harness that a dog cannot back out of, which is how a lot of dogs get loose in the first place.

Four adjustment points, which is what lets you get a genuinely escape-resistant fit. A dog who backs out of a loose harness on a pavement is loose immediately, tracker or not.
If your dog does go missing
The tracker is one tool among several:
- Search the immediate area, calling calmly
- Leave something of theirs outside — their bed, an unwashed jumper. Dogs frequently return to familiar scent
- Ring the microchip database and report them missing
- Ring every local vet, rescue and the dog warden
- Post on local social media with a clear photo and your number
- Physical posters at the site and nearby junctions
- Do not chase. A frightened dog in flight mode runs from their own owner
The one-line version
Buy the tracker if you walk in open country or own a dog who runs. Update the microchip regardless — it takes five minutes and it is the thing that actually brings most lost dogs home.
