@myrabrooks tes the chip works if the dog gets lost. But the way it works is if the person who found the dog takes him or her to a place where they can see of the dog has a chip they pass a machine over the dog where they then they see if the dog has a chip once they detect the dog is chipped then they look for the perons info and call the owner. That's the only way. But it's not a tracking device where you can find with your phone. Sorry. Hope you find your pet soon.
By any chance, did you lose a dog? I ask because my wife found a stranded dog in the streets, in north philly.
Hope this helps 🙏
