Best Dog GPS Trackers Under £40: 6 Tested Picks (2026)

The Critical Difference: Bluetooth vs GPS

Before you spend a penny, you need to understand one thing. Most "GPS trackers" under £40 are not GPS trackers at all. They are Bluetooth finders.

Bluetooth trackers (Apple AirTag, Samsung SmartTag 2, Tile Mate) do not contain GPS chips. They broadcast a short-range Bluetooth signal. When another smartphone in the same network passes within range, it anonymously relays the tracker's location to you. In a busy town centre, this works surprisingly well. On a countryside walk or in a quiet village, it can take 30 minutes or longer between location updates because no one with the right phone is nearby.

True GPS trackers (Tractive DOG 6) contain a GPS receiver and a cellular modem. The device locks onto satellites, calculates its position, and sends that data over the mobile network to your phone in real time. You get live tracking every 2 to 3 seconds. The trade-off is cost: the device is more expensive, and you pay a monthly subscription for the cellular data.

Both types have a place. A Bluetooth tracker is fine for city dogs, dogs that stay in fenced gardens, or as a backup in case your dog slips its collar at the park. A GPS tracker is the right choice if your dog roams off-lead, if you live in a rural area, or if you need real-time tracking during walks and hikes.

Our UK Recommendations at a Glance

We reviewed every budget dog tracker available through Amazon.co.uk and narrowed the field to six. Pricing on Amazon.co.uk differs from the US store, and not all models sold stateside are consistently stocked in the UK, so we focused on trackers with reliable availability.

Pick	Type	Amazon.co.uk Price	Monthly Fee	Best For
Apple AirTag 2	Bluetooth	£29	£0	iPhone owners in towns and cities
Samsung SmartTag 2	Bluetooth	£15 to £22	£0	Android/Samsung owners
Tile Mate (2024)	Bluetooth	£14 to £20	£0 (optional premium)	Mixed-phone households
Tractive DOG 6	GPS	£39 to £59	£3.33 to £9	Real-time GPS tracking
AirTag collar holder combo	Bluetooth	£10 to £18	£0	AirTag owners wanting a secure mount
eufy SmartTrack Link	Bluetooth	£12 to £16	£0	Budget Apple Find My tracker

UK dog owners can also check Argos for Samsung SmartTags and Currys for Tile trackers, though Amazon.co.uk typically offers the sharpest prices, particularly during Prime Day and Black Friday.

1. Apple AirTag 2: Best Overall for iPhone Owners

Check prices on Amazon

The AirTag 2 is the most practical sub-£40 tracker for dogs if you own an iPhone. Apple's Find My network spans over 1 billion devices worldwide, and iPhone density in UK cities and towns is among the highest globally. In London, Manchester, Birmingham, or Edinburgh, your AirTag gets crowd-sourced location updates from the sheer volume of iPhones nearby. Updates typically arrive within 1 to 5 minutes.

The second-generation model launched in January 2026 with a 50% louder speaker (helpful for finding a dog hiding under a hedge), an upgraded Ultra Wideband chip for more precise directional finding, and improved range. Precision Finding now works on Apple Watch, so you can track your dog's direction and distance from your wrist during a walk.

The AirTag itself is not designed as a pet product. Apple does not sell collar mounts. You need a third-party holder that clips or slides onto your dog's collar. Waterproof silicone holders cost £4 to £10 on Amazon.co.uk. Look for one rated IP67 or higher so it survives puddles, rain (and British weather guarantees plenty of that), and the occasional river splash.

Battery life is roughly 12 months on a standard CR2032 coin cell, which costs about £1 to replace at any supermarket or Poundland. No charging cables, no subscriptions, no ongoing costs.

The limitation is straightforward: if your dog escapes into open countryside with no foot traffic, the AirTag will not update until someone with an Apple device passes within Bluetooth range. For urban and suburban dog owners, this is rarely a problem. For rural properties bordering farmland or moors, consider the Tractive GPS instead.

At £29, the AirTag 2 is the best single investment for basic dog tracking. During sales, the first-gen AirTag drops to £12 to £15, which is an even cheaper entry point if you do not need the improved range.

Key specs: Bluetooth + UWB, Apple Find My network, CR2032 battery (12 months), IP67 water resistant, 11g weight, Precision Finding on iPhone and Apple Watch.

2. Samsung SmartTag 2: Best for Android Owners

Check prices on Amazon

If your household runs Android phones (specifically Samsung Galaxy devices), the SmartTag 2 is your equivalent of the AirTag. It uses Samsung's SmartThings Find network, which covers roughly 400 million devices. That is smaller than Apple's network, but Samsung Galaxy phones are popular in the UK, and coverage in cities and towns is solid.

The SmartTag 2 features Bluetooth 5.3 and Ultra Wideband for directional finding on compatible Samsung phones. The compass-style AR view shows you exactly which direction your dog is and how far away, which is genuinely useful when searching around a park or estate. IP67 water and dust resistance means it handles rain, mud, and the general punishment a dog collar takes on British walks.

Battery life is the standout: up to 500 days on a CR2025 coin cell, which is nearly 40% longer than the AirTag. For a device clipped to your dog's collar where you might forget to check the battery, that extra longevity matters.

The SmartTag 2 requires a Samsung Galaxy phone with the SmartThings app. It does not work with iPhones or non-Samsung Android phones. If everyone in your household uses Samsung, this is the pick. If your family has mixed phone brands, the Tile Mate is more flexible.

At £15 to £22 on Amazon.co.uk, the SmartTag 2 is significantly cheaper than the AirTag in the UK. During sales, it drops to £11 to £15. The 4-pack (£40 to £50) brings the per-unit cost under £13, which makes sense if you want trackers on multiple pets.

Key specs: Bluetooth 5.3 + UWB, SmartThings Find network, CR2025 battery (500 days), IP67, 9g weight, compass AR view.

3. Tile Mate (2024): Best Cross-Platform Option

Check prices on Amazon

The Tile Mate works with both iPhone and Android, which makes it the right pick for households where people carry different phone brands. Your partner can see the dog's location from their Android phone while you track from your iPhone. Neither AirTag nor SmartTag offers this cross-platform flexibility.

The 2024 Tile Mate (now branded under Life360) has a 90-metre Bluetooth range, a 3-year non-replaceable battery, and water resistance. The Tile network is smaller than Apple's Find My or Samsung's SmartThings, but the Life360 merger has grown it considerably. In UK cities and larger towns, you still get reliable crowd-sourced updates.

The free tier gives you basic location tracking, last known location, and the ability to ring the tracker. Tile Premium (£2.99/month or £29.99/year) adds smart alerts that notify you if you leave your dog somewhere, a 30-day location history, and free battery replacement. For pet tracking, the free tier covers what most people need.

One practical advantage: the Tile Mate has a built-in hole for attaching directly to a collar ring or keychain clip. You do not need a separate holder like you do with the AirTag. Clip it on, and you are done.

At £14 to £20, the Tile Mate is one of the cheapest trackers on this list. During sales, it drops to £10 to £14. If you just want basic "where is my dog" capability without worrying about phone ecosystems, this is the simplest starting point.

Key specs: Bluetooth, 90m range, Tile/Life360 network, 3-year battery (non-replaceable), water resistant, iOS and Android, built-in attachment hole.

4. Tractive DOG 6: Best Real GPS Tracker

Check prices on Amazon

The Tractive DOG 6 is the only true GPS tracker on this list. It uses GPS satellites and mobile networks to show your dog's exact location on a live map, updated every 2 to 3 seconds. No reliance on nearby smartphones. No crowd-sourced networks. If your dog has mobile signal, you have their location.

This matters in situations where Bluetooth trackers fail: a dog that bolts into a field, a rural escape where nobody is walking past with an iPhone, or a coastal walk where your dog wanders beyond Bluetooth range. The Tractive updates continuously as long as mobile coverage exists.

The tracker clips onto any collar and weighs about 30g, which is comfortable for dogs over 4 kg. It is fully waterproof (IPX7) and the battery lasts 3 to 7 days depending on tracking frequency. Live tracking drains the battery faster. Virtual fence alerts notify you the moment your dog leaves a defined area, which is useful for dogs with garden access.

Beyond location, the DOG 6 monitors heart rate, respiratory rate, and daily activity levels. These health features are not just marketing. Detecting a change in resting heart rate can flag health issues days before symptoms appear. The activity data helps you confirm your dog is getting enough exercise, something the RSPCA and vets consistently recommend monitoring.

The trade-off is cost. The device runs £39 to £59 on Amazon.co.uk depending on sales. The subscription starts at £3.33/month on a 2-year plan, £4.50/month on a yearly plan, or roughly £9/month with no commitment. First-year total cost is roughly £80 to £130 depending on your plan. That is significantly more than a £29 AirTag, but you get genuine GPS tracking that works anywhere with mobile signal.

At £39 during sales, the Tractive DOG 6 fits within this budget. Regular price is closer to £50 to £59. Prime Day and Black Friday typically bring it to £35 to £45, which is when we recommend buying.

Key specs: GPS + cellular (LTE-M), live tracking every 2 to 3 seconds, virtual fence, heart rate and respiratory monitoring, IPX7 waterproof, 30g, 3 to 7 day battery, Tractive app (iOS/Android). Subscription required.

5. Waterproof AirTag Collar Holder: Best Accessory

Check AirTag collar holders on Amazon

If you already own an AirTag (or plan to buy one), you need a secure collar mount. The AirTag was not designed for pets, so the holder needs to keep it locked in place during running, rolling, swimming, and general dog chaos. British walking conditions (muddy fields, rainy paths, river crossings) demand a waterproof holder.

The best holders are made from silicone or TPU with a snap-lock closure that prevents the AirTag from popping out. Look for IP67 or IP68 waterproof ratings. Avoid holders that just slide the AirTag into a pouch, because dogs will shake them loose within a week.

Integrated AirTag collars (a collar with a built-in AirTag pocket) are the most secure option. These run £10 to £18 on Amazon.co.uk and eliminate the risk of the holder detaching from the collar. Tactical-style collars with built-in AirTag compartments are popular for larger, more active dogs.

For standalone holders that attach to an existing collar, expect to pay £4 to £8 for a 2-pack. Look for composite silicone designs that are durable and lightweight enough that your dog does not notice the extra weight.

This is not a tracker by itself. It is the accessory that makes the AirTag viable as a pet tracker. Budget £35 to £40 total for an AirTag 2 plus a quality waterproof holder.

What to look for: IP67+ waterproof rating, snap-lock or screw closure, fits collar widths 1 to 2.5 cm, lightweight (under 15g).

6. eufy SmartTrack Link: Best Budget Find My Tracker

Check prices on Amazon

The eufy SmartTrack Link is a Bluetooth tracker that works on Apple's Find My network at a fraction of the AirTag's price. At £12 to £16 for a single unit on Amazon.co.uk, it is the cheapest way to get into the Find My ecosystem for pet tracking.

The SmartTrack Link has a slightly larger form factor than the AirTag but includes a built-in hole for direct collar attachment. No separate holder needed. The battery (CR2032) lasts roughly 12 months. It is water resistant (IPX5, so it handles rain but should not be submerged) and weighs 10g.

Because it uses Apple's Find My network, you get the same crowd-sourced location updates as the AirTag, backed by 1 billion+ Apple devices. The trade-off is no Ultra Wideband, which means you do not get Precision Finding with directional arrows. You get a general location on the map, but not "your dog is 5 metres to the left" precision.

For UK dog owners who want basic location awareness without paying £29 for an AirTag, the eufy SmartTrack Link is a smart compromise. It also works as a spare tracker for a second pet or a backup on your dog's harness.

One caveat: it does not work with Android phones. iPhone only, through the Find My app.

At £12 to £16, this is the cheapest tracker on the list. During sales, 2-packs drop to £16 to £20. If you want to track two pets on a tight budget, the eufy 2-pack is the best deal available.

Key specs: Bluetooth, Apple Find My network, CR2032 battery (12 months), IPX5 water resistant, 10g, built-in attachment hole, iPhone only.

Which Tracker Is Right for Your Dog?

The right pick depends on where your dog spends time and which phone you carry.

City dog, iPhone owner: Apple AirTag 2. The Find My network is dense in UK cities and towns, and updates come quickly. Add a £6 waterproof collar holder and you are set.

City dog, Samsung owner: Samsung SmartTag 2. Same concept as the AirTag, built for the Samsung ecosystem. Longer battery life, and cheaper in the UK at £15 to £22.

Mixed-phone household: Tile Mate. Works with iPhone and Android. Clips directly onto the collar. No ecosystem lock-in.

Rural property, off-lead dog, or escape risk: Tractive DOG 6. The only option on this list that tracks in real time regardless of nearby phones. Worth the subscription if your dog has access to open countryside.

Budget pick, iPhone owner: eufy SmartTrack Link. Same Find My network as the AirTag at half the price. No Precision Finding, but location updates work the same way.

Already own an AirTag: Get a proper waterproof collar holder. The £4 to £8 investment makes your existing AirTag a reliable pet tracker.

Honest Limitations

No tracker under £40 is foolproof. Here is what each type cannot do.

Bluetooth trackers cannot track a dog in real time. They update when a nearby phone relays the signal. In a busy high street, updates arrive every 1 to 5 minutes. In the Cotswolds or the Lake District, you might wait 30 minutes or get no update at all. If your dog bolts across a farmer's field, a Bluetooth tracker will show you the last known location where someone with a phone walked past, not where your dog is right now.

GPS trackers need mobile signal. The Tractive DOG 6 is useless in areas with no coverage. Parts of rural Scotland, Wales, and Cornwall have patchy mobile reception, which means intermittent tracking updates. The tracker stores location data locally and uploads it once signal returns, but that does not help in the moment.

No tracker replaces a secure collar, a microchip, and ID tags. UK law requires dogs to be microchipped (The Microchipping of Dogs (England) Regulations 2015, with equivalent laws in Scotland, Wales, and Northern Ireland). A tracker is one additional layer of protection. A microchip (scanned at any vet or rescue centre) is permanent identification that cannot fall off, run out of battery, or lose signal. Use both.

When to Buy in the UK

Prime Day (July): Best event for AirTags, SmartTags, and Tile trackers on Amazon.co.uk. Expect 25 to 40% off. First-gen AirTags dropped to £11 to £13 during Prime Day 2025.

Bank Holiday sales (May, August): Argos and Currys occasionally discount Samsung SmartTags and Tile trackers during bank holiday weekends. Amazon.co.uk tends to match or undercut these prices.

Black Friday and Cyber Monday (November): Tractive runs its deepest device discounts here, often bundling the tracker with 6 months of subscription credit. AirTag multi-packs hit their annual low.

Boxing Day and January sales: Leftover Christmas stock creates opportunistic deals, especially on Samsung and Tile trackers at Currys and John Lewis.

Lightning deals (throughout the year): Bluetooth trackers surface in Amazon.co.uk lightning deals two to three times monthly. Our deal channels flag these automatically.

The Verdict

You have two real options under £40: a Bluetooth finder that works through crowd-sourced networks (best for city and suburban dogs), or a GPS tracker at the top of the budget that provides real-time satellite tracking with a monthly subscription (best for rural and off-lead dogs). Both are worth the money for the peace of mind they provide.

Start with the AirTag 2 or SmartTag 2 if your dog mostly stays in populated areas. Step up to the Tractive DOG 6 if you need reliable tracking in open spaces. And whatever you choose, pair it with your dog's microchip and ID tags. A £29 tracker on a collar is not a replacement for permanent identification.
