Can you use an AirTag to track your dog?

AirTags are brilliant for finding lost keys. But can you use an AirTag to track your dog? Based on our field test results, it’s unlikely to be able to find your dog quickly, especially if they are in the countryside.

Airtags don’t work for dogs

Many dog owners have tried clipping an AirTag onto their dog’s collar. They’re small, affordable, and lots of people already have one at home. At first glance, it feels like a simple way to keep tabs on your dog.

The reality is a bit different. AirTags were designed to find lost items like keys or bags. They don’t use GPS and they rely on nearby Apple devices to update their location. If your dog runs off into the countryside, a quiet park, or anywhere without people nearby, the location often stops updating just when you need it most.

To see how this works in practice, we ran a simple real-world test comparing an AirTag with a specialist dog GPS tracker, PitPat GPS. On this page, you’ll see exactly what happened and how the two approaches perform when a dog actually goes missing.

AirTag vs Dog GPS Tracker – Field Test

Purpose of the experiment (What we wanted to test)

The purpose of the experiment was to determine how effective an Apple AirTag might be for finding a dog that had failed to return or become lost whilst walking off-lead with its owner, and to compare the performance of the AirTag with a specialist dog GPS (satellite) tracker device from PitPat.

How an Apple AirTag works

Apple AirTag is a small device powered by a coin-cell intended to allow a user to track lost inanimate objects (Apple specifically documents that it should not be used on humans or animals). It relies on passing iPhones which detect its presence when they are within a few 10’s of meters, report their own location to Apple, which then forwards the information to the iPhone belonging to the owner of the AirTag. An AirTag thus reports the location of the iPhone that most recently passed close enough to it to detect its signal, and is reliant on this chance proximity to track a lost object.

How a PitPat Dog GPS Tracker works

PitPat Dog GPS Tracker is a small, robust device powered by a rechargeable battery intended to be fixed to a dog’s collar to allow the user to track the dog whilst out walking. It receives GPS satellite signals in real-time and returns the calculated location to the user’s smartphone via the cellular mobile phone network. Because it has a two-way connection, it can be commanded by the user to return real-time continual tracking information, requiring only mobile coverage and not the presence of a nearby iPhone to do so.

Experimental design (How we did the experiment)

Three small boxes, each containing an Apple AirTag and a PitPat Dog GPS Tracker were placed in three different locations and left unattended for 24 hours. The first two of the three locations were chosen to be characteristic of places where dogs might get lost (typical off-lead walking areas in country parks, etc). A third location was chosen to maximise the performance of the AirTag (by placing it in a very populated area, a supermarket car park) so that we could understand the AirTag’s theoretical best performance.

On each of the thirteen hours between 06:00 and 18:00 on a weekday (the hours of daylight being typical dog walking times), the AirTag and the GPS tracker were asked for their location using their respective apps on a smartphone a few km away, mimicking what might happen had they been on the collar of a lost dog, with the owner attempting to locate their pet as quickly as possible. This effectively simulated 39 distinct “lost dog” events during the day.

It is not possible to command an AirTag to measure and send a location fix on demand, so we instead recorded how ‘old’ the last (most recent) fix was. This gives an indication of the value of the AirTag’s location fix for finding a lost dog because – assuming the dog is moving around – an older location fix will be less informative (less precise) than a newer (more recent) fix. There is no live-tracking mode for Apple AirTags, so only the most recent historic fix was available.

For the PitPat Dog GPS Tracker, we asked it on each occasion to enter its live-tracking mode, and measured how long it took to do so as an indication of how rapidly a lost dog would be found. Once in live-tracking mode, fresh location fixes were then automatically returned from the PitPat Dog GPS Tracker as frequently as every 10 seconds, which would allow a moving dog to be followed.

Experimental conclusion (What we learned)

At the end of the experiment we calculated the mean values for the “time to first fix” (PitPat) and “age of most recent fix” (AirTag). Across all 39 test events, this revealed that Apple AirTag’s data was at least one hour and 12 minutes out of date, and at worst over 24 hours out of date (with no subsequent live-tracking updates). PitPat GPS Tracker took on average between 20 seconds (best case) and 97 seconds (worst case) to get a first fix on a dog (with live updates every 10 seconds afterwards),

Consequences

Whilst Apple AirTag may be a superficially appealing choice for tracking a dog (it is low cost, has a long battery life, and no subscription), and indeed it is popular in that role, its real-world tracking performance (speed) as proven in this experiment makes it wholly-unsuitable for that task. It is also physically unsuitable, because it is not waterproof, its mechanical design is not intended to withstand a dog bite, and it contains a battery that could be harmful to a dog if chewed or swallowed. The PitPat GPS Tracker is designed specifically for finding a lost dog and is tough enough to be used on a dog’s collar. Like AirTag it requires no subscription. This experiment has shown that it demonstrably provides live-tracking in real-world conditions that is over 200 times faster than Apple AirTag making it the clearly superior choice for tracking a dog.

Frequently Asked questions

You can attach an AirTag to your dog’s collar, but as our experiment shows, its real-world tracking performance makes it unsuitable for tracking your dog.

A PitPat Dog GPS Tracker uses satellites and mobile networks to show your dog’s location on map in real time, wherever there’s coverage.

AirTags don’t use GPS or their own mobile connection. They rely on Bluetooth and Apple’s Find My network. If there are no Apple devices nearby, they won’t update location.

Dog GPS trackers like PitPat use GPS satellites and mobile networks. Both the tracker and your phone need signal for live tracking to work.

An Airtag:

Uses Bluetooth.
Relies on nearby Apple devices.
Designed for keys, bags and luggage.

A PitPat Dog GPS Tracker

Uses GPS satellites.
Has its own mobile connection.
Designed to attach securely to collars and harnesses.
Built for outdoor use.

AirTags can be accurate in busy areas with lots of Apple devices nearby – however in our experiment, AirTags underperformed even in a busy supermarket car park. If you manage to get a location, it is highly likely to be out of date by the time you reach the area if your dog is moving around.

A dog GPS tracker like PitPat provides real-time location updates in areas with mobile coverage, so you can keep track of where your dog is at all times.

Attaching any electronic device to your dog’s collar or harness carries some risk. The main one is chewing or ingestion if it comes loose.

AirTags were not designed for pets. They’re small, smooth and easy to dislodge when used with third-party collar holders. If a dog manages to remove one, it can be swallowed. Because of their size and coin-cell battery, ingestion can cause:

Gastrointestinal blockages
Internal burns from the battery
In severe cases, emergency surgery

The risk isn’t guaranteed, but it is real, particularly with strong chewers.

Specialist dog GPS trackers are:

Designed to be securely fixed to a collar.
Larger and harder for a dog to swallow.
Built with pet behaviour in mind (scratching, rolling, chewing).
Tested for durability under rough use.

No device is completely risk-free, but purpose-built trackers are engineered specifically to reduce the risk of your dog tampering with the device.

With a PitPat Dog GPS Tracker, updates pause if there is no satellite or mobile signal. The location will refresh once coverage returns.

With an AirTag, updates depend on nearby Apply devices. If none are present, the location will not update.

In rural areas, AirTags are less reliable because fewer Apple devices are nearby.

A PitPat Dog GPS tracker is generally more suitable in rural areas, provided there is mobile coverage.

GPS signals can struggle indoors or underground. If your dog is inside a building, updates may pause until they return outside or regain signal.

AirTags may update indoors if Apple devices are nearby.

No. Unlike some other dog GPS trackers, PitPat is available without a subscription for core tracking and activity monitoring features.
