At Smart Bark, we love the latest dog tech, and having used an AirTag on our car keys, the question quickly became: could we use one to help track a dog?
AirTag tracking devices were launched by Apple and have become one of the most popular tracking solutions around. Small, light, affordable and genuinely easy to use, they were originally created to find keys, wallets and other items that go missing.
But many dog owners across the UK have found them to be a surprisingly capable option for keeping tabs on their dog too.
Whilst AirTags weren't designed specifically to track your dog, they're a low-cost, user-friendly and reliable option with exceptionally long battery life. We look at the pros and cons compared to GPS trackers below.
💡 Want 100% real-time tracking? If you need to track your dog at any given time, in any location, you should invest in a GPS tracker built for dogs. Read our deep-dive: Best GPS Trackers for Dogs

This buying guide will help you figure out if using an Apple AirTag is the right choice for your dog, and we've rounded up and tested the best AirTag dog collars and holders available in the UK.

4. Our Verdict
6. FAQs
Possibly! What's undeniable is that AirTags have some great qualities that rival even the best GPS trackers for dogs on the market and at a far lower price.
AirTags are splash, water, and dust resistant and exceptionally light, so they make an ideal tracking device for your four-legged friend.
But they also have critical weaknesses that may make them unsuitable for some dog lovers. Before you decide, let's take a look at how AirTags work versus traditional GPS trackers.
Unlike dog trackers, AirTags don’t use GPS technology, and they don’t connect to the internet.
They use secure Bluetooth signals informing you of their location. You can access their location if you open your “Find My” app on your Apple device.
However, if your dog runs away, or gets lost, the AirTag won't be in your Bluetooth range anymore. So how do you track your dog then?
You can still locate your dog anywhere, because the AirTag can talk to other people's iPhones, and borrow that iPhone's GPS and 4G connectivity to tell you where they are.
Equally, if someone finds your dog and sees the AirTag, they can tap it and see the information you provided, such as your name and phone number, and contact you immediately.
With almost a billion iPhones on the planet, there's a pretty good chance that a lost AirTag will get the chance to phone home to you at some point, making this potentially a more reliable tracking system than some others on the market.
That really depends on where you live. If you live in an urban area, they will be very effective. More people, means more Apple iPhone users.
However, they’re not an ideal solution in more remote areas of the UK where there will be considerably less Apple devices about. You won’t be able to track your dog if it runs away across fields since there will be no devices nearby that can mark the location of your AirTag.
In short, if you have a canine Harry Houdini and you feel you need to track your dog all the time, we would suggest a GPS tracker designed specifically for dogs.
If, on the other hand you live in an urban area and you're simply looking for a little more peace of mind than your dog's collar ID tag can provide, for significantly less money, then an AirTag is an ideal option.
The simple answer is yes. As the AirTag itself is simply a metal disc, it needs a protective holder to attach to your dog’s collar. You have two options available to you :-
A specialised collar which secures the AirTag in an anti-slip pocket so that it can't fall out when your dog runs and shakes.
An AirTag holder which simply attaches to your dog’s favourite collar (or harness in some cases).
All the AirTag holders we feature attach to the collar at both the top and bottom of the tag so they don't hang down annoying your dog and potentially catching on something.
In short, the only way the AirTag accessories we feature will come off your dog, is if you remove the whole collar.
Since AirTags were not designed for dog tracking, Apple doesn’t offer any official dog collar accessories.
We've discovered a whole range of nicely designed products to keep your AirTag firmly attached to your dog from bespoke collars to protective cases.
Bark + Shout is a London-based brand that has built a loyal following among dog owners who want an AirTag collar that's both discreet and genuinely functional.
The collar features their registered TagPouch™ design, an internal pouch on the inside of the collar that completely hides the AirTag from view, making it far less visible to anyone who might want to remove it.
The pouch uses a strong velcro fastener to hold the AirTag securely in place. To change the battery, simply peel back the pouch, pop in a fresh CR2032, and you're done.
For added security, Bark + Shout offer an optional Fidlock buckle upgrade (see photo). A clever magnetic-mechanical fastener that replaces the standard buckle, making the collar virtually impossible to remove accidentally whilst still allowing quick, one-handed release when you need it.
Having tested it, we feel it's an ideal upgrade for anyone with reduced hand strength or wanting to open their dog's collar one-handed.
Whichever option you opt for, the collar itself is water-resistant, features reflective strips for night visibility, and is available in three different lengths and in two width choices - 2.5cm and 4cm.
We tested the slim 2.5cm collar in Oak Tan and found the AirTag needed a firm push to slot into the pouch. But once in, it wasn't going anywhere. Out of sight, out of mind, exactly as intended.
The collar held up well on muddy walks and the AirTag didn't budge. Made from lightweight nylon webbing, it's a no-frills design, comfortable enough for most dogs, though worth noting there's no padding if your dog has more sensitive skin.
Available in a range of 6 colours - Oak Tan (we tested), Cranberry Red, Carbon Black, Midnight Blue, Alpine Green & Graphite Grey.
Customer reviews are strong, with a 4.2-star average across 148+ reviews and we should mention that there's free shipping on orders over £40.
Our Verdict : A clever, discreet design that hides the AirTag inside the collar rather than on top of it. Ideal for dog owners who want tracking to be low-key.
Reasons to Buy
+ AirTag hidden inside the collar, much more discreet
+ Registered TagPouch™ design
+ Water-resistant with reflective strips
+ Made in London, UK
+ Sizes from S to XL
+ Fidlock technology optional
Reasons to Avoid
- Pouch is tight so tricky to get the AirTag in and out
- More expensive option than a simple holder fitted to your existing collar
If you already have a favourite collar and are simply looking for a holder to attach your AirTag, there are some great options on the market. We've extensively tested a whole range of holders and these are the ones we would recommend.

If you're already a BullyBillows fan then this is the natural choice to add AirTag tracking to your existing setup or it can be added to any brand of collar.
The BullyBillows AirTag Holder is crafted from high-grade silicone and designed to sit securely on any collar without adding bulk or dangling.
With three sizes to choose from, it fits BullyBillows' own Combat Collar widths (available in 2.5cm, 4cm and 5cm options), making it one of the few holders explicitly designed to accommodate wider collars suited to larger, stronger breeds.
The holder is lightweight and flexible with subtle BullyBillows branding, and comes in three colours.
We tested their small holder and found it slid onto our dog's collar easily, stayed put during active walks, and the AirTag felt snug and protected inside.
Our Verdict : The obvious pairing if you already use BullyBillows gear. It's one of the very few holders that comfortably fits wider 4cm and 5cm collars, making it a top pick for large breed owners.
Reasons to Buy
+ Fits 2.5cm, 4cm & 5cm collar widths
+ Ideal for large and strong breeds
+ Lightweight high-grade silicone
+ Pairs perfectly with BullyBillows Combat Collars
+ Three colour options
Reasons to Avoid
- Only available direct from BullyBillows (not on Amazon)
- BullyBillows branding won't suit everyone
If you are looking for an AirTag holder that will stay put no matter what your dog throws at it, then take a closer look at TagVault™ from Elevation Labs.
This collar mount is IP69 waterproof, doesn't dangle down and fits all collar widths and harnesses. It uses self-piercing screws to attach through your dog's collar, so it is ultra-secure and can fit any collar width.
With a durable composite construction it also features an unbreakable ballistic Nylon6 polyamide backplate. Basically, it's built to withstand anything your dog or the environment throws at it !
Changing the battery is a little more in-depth than our other options but not difficult. Simply undo the four small screws on the front plate, leaving the backplate still fixed to your dog's collar.
Change the battery and screw the front plate back in place.
It will suit all collars up to 5mm thick (which is pretty much all collars apart from very thick leather collars).
Our Verdict : Amazingly durable, pierces collars cleanly and sits flush. Slightly more involved in assembly and battery changing.
Reasons to Buy
+ IP69 waterproof rating
+ Ultra-secure screw-through attachment
+ Fits virtually any collar or harness
+ Glow in the dark option
Reasons to Avoid
- Not the cheapest holder
- Requires a screwdriver for installation
Case-Mate is the industry leader in stylish and well designed phone cases and mobile accessories, so they know a thing or two about keeping our tech safe.
They have extended their range to include AirTag cases with some aimed at pets.
We particularly liked this case which is available in a 'Glow in the Dark' white making it perfect for late night walks.
All their range is water-resistant so perfect for those dogs that love to swim. It has a durable outer shell and after inserting your AirTag it simply threads onto your dog's collar.
Suitable for collars measuring up to 2.5cm wide. It's lightweight so your dog won't even know it's there and is also available in black and an eye-catching lime green.
Our Verdict : A nicely designed, well-built case that feels secure and looks good. We found the glow-in-the-dark option really helpful for night walk safety.
Reasons to Buy
+ Good quality
+ Sturdy design
+ Colour options
+ Glow in the Dark option
Reasons to Avoid
- Only suitable for smaller collars
This AirTag case from Flirtare is designed to fit on slim collars so will be perfectly suited to small dogs, puppies or even cats.
Fitting flush on your dog's collar, these silicone AirTag holders are available in 3 sizes and 6 colours.
When testing, we felt that they threaded really easily onto your dog's collar and the front hollowed out pattern is designed to ensure that it doesn't muffle the AirTag noise.
During testing, the large holder was a snug fit on a 2.5cm (1 inch) medium-width collar, making them best suited to small and medium breeds. They also offer smaller holders for a 0.4cm and a 1.9cm collar.
They're a solid everyday choice, but we feel that if your dog is the type to hurl themselves through hedges and brambles, you'd be better served by the TagVault™ Collar Mount or Bark + Shout AirTag Collar, both of which offer greater peace of mind for more adventurous dogs.
They add minimum weight to the collar and are scratch proof.
Our Verdict : A great value, well-designed holder for slim collars. The go-to option for small breeds, puppies or cats.
Dimensions : for collar widths 0.4, 1.9 and 2.6cm
Reasons to Buy
+ Specifically designed for slim collars
+ Ideal for small dogs, puppies and cats
+ Won't muffle AirTag speaker
Reasons to Avoid
- Not designed for wide collars

AirTags are an excellent middle ground between relying on a microchip alone and investing in a dedicated GPS tracker.
They're affordable, easy to use and genuinely effective for most everyday situations, particularly if your dog goes missing locally where there are iPhone users nearby.
Just be realistic about their limitations: AirTags rely on Apple's Find My network (nearby iPhones) rather than live GPS, so they won't show you real-time location updates. In rural areas with fewer iPhones around, coverage can be patchy.
If you live with a true escape artist or regularly walk in remote countryside, a dedicated GPS tracker will serve you better.
🔗 You may also enjoy our popular review of the best dog harnesses, including an escape-proof option from Snootiful Hound.
Dedicated GPS trackers such as Tractive, PitPat, Pawfit and Kippy offer live tracking that updates every few seconds, virtual fence alerts and activity monitoring.
Most require a monthly subscription, though plans start as low as £3.75 per month. They need cellular network coverage to work but most brands offer a 30-day money-back guarantee so you can test coverage in your area.
We've tested a lot of GPS Trackers over the years and only the best made it to our review.
If tracking activity levels is your priority rather than location, activity monitors like PitPat, Pooch Play and FitBark are worth exploring.
Think of them as a Fitbit for dogs, collar-mounted sensors monitor movement and rest to build a picture of daily activity.
Can I use an AirTag to track my dog in the UK?
Yes. While Apple didn't design AirTags specifically for pets, thousands of UK dog owners use them effectively. They work via Apple's Find My network. Nearby iPhones detect the AirTag's Bluetooth signal and report its location. The more iPhones in your area, the more effective it will be.
What's the difference between an AirTag and a GPS tracker for dogs?
An AirTag uses Bluetooth and Apple's Find My network and has no subscription cost. A GPS tracker uses live cellular or satellite tracking and typically requires a monthly subscription (from around £3.75/month) although PitPat offer a no-subscription GPS Tracker.
GPS trackers show real-time location anywhere with mobile signal; AirTags depend on nearby iPhones.
How do I attach an AirTag to my dog's collar?
You'll need either a purpose-built AirTag collar (like Bark + Shout) or a separate holder/case (like TagVault™, BullyBillows or Case-Mate) that attaches to your existing collar.
Which AirTag collar is safest so the AirTag can't be removed?
The Bark + Shout TagPouch™ hides the AirTag inside the collar making it the most discreet. The TagVault™ uses screw-through attachment making it the hardest to remove accidentally. Both are excellent if security is your main concern.
Do AirTag holders work on wide collars for large dogs?
Most holders are designed for standard 2.5cm collars. The BullyBillows AirTag Holder is one of the few that explicitly fits 4cm and 5cm width collars, making it the best choice for large or powerful breeds.
How long does an AirTag battery last on a dog collar?
The CR2032 battery in an AirTag is rated for over a year. Replacement batteries are widely available and inexpensive. Most holders allow battery access without removing the holder from the collar.
