An AirTag on the dog collar can help find a lost collar or a dog in a busy environment. However, it is not a GPS tracker that continuously independently transmits a live location. Therefore, see an AirTag as an additional tool and not as a replacement for a chip, name tag, good fence or special tracking system.
How an AirTag determines location
An AirTag uses Bluetooth and Apple's Find My Network. If a suitable Apple device comes nearby, the approximate location can be safely passed on to the owner. According to Apple, this network consists of more than a billion devices.
That works differently than a GPS tracker with its own mobile connection. An AirTag does not have an independent subscription and does not continuously transmit its own location everywhere. In a busy residential area, a location can be updated faster than in a quiet nature reserve where few suitable devices are used.
When an AirTag can be useful
An AirTag can be useful when your dog wanders away in a built-up area or when you want to find a lost collar. If the AirTag is nearby and you are using a suitable iPhone model, an accurate search can help determine the direction and distance.
You can also mark an AirTag as lost. Someone who finds it can read the AirTag with a suitable phone and see the contact information you have made available.
Why it's not a full-fledged dog tracker
A special GPS tracker is made to track an animal or object at a distance and usually uses its own connection. An AirTag is intended by Apple to find personal items. The location depends on devices in the area and may therefore be delayed or temporarily unavailable.
A full battery, working settings and range also play a role. Therefore, do not expect an uninterrupted route or guaranteed live location. If you want to be able to actively monitor while walking or on holiday, compare systems that are specifically made for this purpose.
Attach it without disturbing the wearing comfort
Choose a holder that fits the AirTag securely and does not protrude sharply. The collar should still fit normally and should not become heavier or stiffer than is comfortable for your dog. Check regularly whether the holder, collar and closure are intact.
Do not hang a large bundle with AirTag, medal and other accessories on one small ring. This can rattle, catch on branches or hit the chest. Use a solution that suits your dog's size and behavior.
An AirTag is splash and water resistant according to Apple's technical specifications, but not indestructible. Check it after swimming, mud and wild play and follow Apple's instructions for cleaning and battery replacement.
Chip and nameplate remain important
A chip does not work as a live tracker, but can be read by a vet or shelter to find a registered owner. Therefore, make sure that the registration is up to date. A clear name tag often makes direct calling even faster.
The safest approach consists of several layers. Prevent escape, use a well fitting collar or harness, keep the chip registration up to date and only add a tracker that suits the risk and your walking environment.
Frequently asked questions
Is an AirTag the same as a GPS tracker for dogs?
No. An AirTag uses Bluetooth and devices on the Find My Network. A GPS tracker usually uses its own location and mobile connection to allow for more frequent remote updates.
Can I track my dog live with an AirTag?
Not guaranteed. The location is updated when compatible devices nearby detect the AirTag. In a quiet environment, updates may not be forthcoming.
Can an AirTag be attached to any dog collar?
Only when a suitable holder fits securely without chafing, becoming heavy or protruding. Check the confirmation regularly.
Does an AirTag replace my dog's chip?
No. Keep the chip registration up to date and preferably use a name tag with contact information.
Is an AirTag waterproof?
Apple describes the AirTag as splash and water resistant under testing conditions. Water resistance may decrease and is not the same as indefinitely waterproof.
