Gonna leave that other thread behind.
...Also, anyone use Apple tags on a pooch? ...
Apple tags don't work for field dogs. They emit a short range Bluetooth signal. The reason it works on luggage and suchlike is the handlers who have an iPhone; the iPhone automatically sends the signal to the 'Cloud' where the registered user can see where it is. All unknowing to the handler, and Android phones won't do it.
