A GPS tracker shows you where your dog is on your phone, and can warn you the moment it leaves home. It only helps if it is charged, fitted well and set up before the day you need it. This guide covers charging and fitting, setting up a safe zone, a test walk, good battery habits, and what to do if your dog goes missing. It also explains why a tracker is an extra layer of safety, not a replacement for an ID tag and a microchip.
How we wrote this: the advice comes from Dogs Trust’s guide on finding a lost dog, Battersea’s dog microchipping advice, and the product pages for two trackers we list, Tractive DOG 6 and Fi Mini. Other product facts come from our product pages, which cite the makers and reviewers. We put their advice in our own words and mark our own tips with “in our view”. All were checked on 2 November 2026. We did not test any trackers for this guide, and we do not show prices or ratings. Most trackers need a paid plan; check the current terms on the maker’s site.
What a GPS tracker does, and does not do
Most consumer trackers combine GPS with a mobile data connection. Tractive explains that each of its units carries its own SIM, much as a phone does, and relies on mobile networks to send the location to your app, and that the subscription covers those data fees. Fi lists live GPS location, escape alerts when your dog leaves a zone you set, and a mode for helping others search.
In our view, that makes a tracker very good at one job: telling you quickly where your dog is. It cannot help if the battery is flat, the signal is poor, or the tracker falls off. That is why the basics still matter.
Keep the ID tag and microchip
A tracker is not a form of ID. Battersea notes that in England, Wales and Scotland the law requires dogs to be microchipped and to wear a collar with an ID tag. It explains that vets, wardens and rescue centres can all scan a chip to find the owner, and that you must keep your contact details on the chip database current.
In our view, a stranger who finds your dog will read the tag and a vet will scan the chip; few will know what to do with a tracker. Keep all three. Our guide on what to put on a dog ID tag covers the details to include. Ask your vet about microchipping if your dog is not chipped yet.
Step 1: choose a tracker that fits your dog
Trackers differ mainly in size, battery life and how they attach. Two from our catalog:
- Tractive DOG 6 GPS Tracker: a clip-on tracker for dogs above about 9 pounds, for collars up to 1.1 inches wide. Our product page lists battery life of up to 6 days, or up to 14 days with Power Saving Zones, and an IP68 waterproof rating. A subscription is required.
- Fi Mini GPS Tracker for Dogs: a very small 0.56 ounce unit that goes on any collar in a silicone case. Fi rates it for up to 2 months per USB-C charge. Live tracking and escape alerts need a paid Fi plan.
Our best GPS dog tracker guide compares more options, including trackers for hunting and remote areas. In our view, check the maker’s coverage map for your area before you buy, since a cellular tracker depends on mobile signal.
Step 2: charge it and set up the app
In our view, do the setup indoors, before the tracker goes on your dog:
- Charge the tracker fully, following the maker’s instructions.
- Install the maker’s app, create an account and activate the tracker; with most brands this is when you choose a plan.
- Add your dog’s profile and a recent photo, which helps if you need others to search.
- Invite a second person in your household, so more than one phone gets alerts.
- Turn on notifications for escape and low battery alerts on every phone.
Step 3: fit it on the collar
A tracker that hangs loose can twist, rub or come off. In our view:
- use the clip, strap or case the maker supplies, and check it matches your collar width; Tractive lists collars up to 1.1 inches for the DOG 6, and Fi supplies cases that attach to any collar,
- fit the collar so you can slide two fingers under it, snug enough that it cannot slip over your dog’s head,
- put the tracker at the top of the neck, where it gets the clearest view of the sky,
- check the fit and the clip every few days, and after rough play or swimming.
If your dog is new to collars, see how to get a puppy used to a collar and leash first, and how to measure a dog for a collar for sizing.
Step 4: set a safe zone
A safe zone, or virtual fence, is an area you draw in the app. Tractive and Fi both send an alert when your dog leaves it. In our view:
- draw the first zone around your home and garden, a little larger than the fence line, to cut false alarms,
- add zones for places your dog stays often, such as a relative’s home,
- use home Wi-Fi or a home base if your tracker offers it; Tractive says its Power Saving Zones extend battery life, and our product page notes a reviewer found Fi Mini alerts slower without Fi’s home base.
Step 5: do a test walk
In our view, test the tracker before you rely on it:
- Ask a family member to take your dog for a short walk while you watch the live map at home.
- Check that you get the escape alert when they leave the safe zone, and how long it takes.
- Note any spots where the signal drops, such as woods, valleys or inside large buildings.
- Try the light or sound feature, if your tracker has one; Tractive lists an LED light and a sound tone to help you find the tracker.
Repeat the test in places you walk often, so you know how the tracker behaves there.
Using a tracker off-lead and on trips
In our view, a tracker is a backup for good recall, not a reason to skip training. Before you let your dog off-lead in a new place, practise recall on a long line; see how to use a long line for dog training. On hikes and trips:
- check the signal on the live map when you arrive, before letting your dog off,
- set a temporary safe zone around a holiday home or campsite if your app allows it,
- remember that cellular trackers can lose signal in remote areas; our best GPS dog tracker guide covers handheld systems made for places without coverage,
- update the tag with a mobile number you will answer while you are away.
Step 6: build good battery habits
A flat tracker is just a weight on the collar. In our view:
- charge on a fixed day each week, or whenever the app shows it below about a third,
- top it up before trips, hikes and holidays, and on bonfire night and other noisy evenings when dogs are more likely to bolt,
- turn on low battery alerts, and keep a charger in the car or travel bag,
- expect shorter battery life in cold weather and with frequent live tracking.
If your dog goes missing
Open the app and use live tracking straight away, then follow the dot. If you cannot reach your dog quickly, or the tracker is off or out of range, follow the steps Dogs Trust sets out:
- contact the dog warden for your local council and the neighbouring areas, since dogs can travel far,
- call local vets, kennels and rescue centres in case your dog has been handed in,
- tell your microchip database your dog is missing; Dogs Trust notes it can alert you if someone tries to change the chip details,
- put up posters and share clear photos and your contact details on local social media groups.
If your dog comes back injured or unwell after time away, have it checked by your vet.

FAQ
Do GPS dog trackers need a subscription?
Most cellular trackers do. Tractive explains that its subscription pays for the mobile data used by the tracker’s built-in SIM, and Fi’s live tracking and alerts need a paid plan. Check the current terms on the maker’s site.
Can a GPS tracker replace a microchip?
No. Battersea explains that vets, wardens and rescue centres scan microchips to find owners. A tracker helps you find your dog; a chip and an ID tag help others return it.
Where should a GPS tracker sit on a dog’s collar?
In our view, at the top of the neck, attached with the maker’s clip or case, on a collar fitted so two fingers slide underneath.
How often do I need to charge a dog GPS tracker?
It depends on the model and settings. Tractive lists up to 6 days for the DOG 6, or up to 14 with Power Saving Zones; Fi rates the Fi Mini for up to 2 months. Live tracking and cold weather use more battery.
