>Yes, the AirTag is a bluetooth device. But in the past I had to add any bluetooth device (like headphones) to my iPhone bluetooth. Otherwise, it would try to read many devices around me (at the gym or whatever). But this AirTag does not need to be added. At least, for me, this is the first time I came across a bluetooth device that works without adding it.

Which is exactly the scary part. How many such apps may install themselves with you knowing nothing about them?

If you now know, without having to lift a finger, where the dog is, think of how many big dogs can say the same about knowing where you are.
