It’s one of the worst feelings a pet owner can have…when theirs goes missing.

More dogs and cats go missing around the Fourth of July than any other time of year, so it might be time to sign up for FidoAlert.

FidoAlert is a free lost pet service much like the Amber Alerts you get on your phone.

Sign up and they’ll send you a free I.D. tag with their name on it and a QR code and if someone finds your pet and scans the QR, you get a text and email to let you know they’ve been found!

Lifehacker has more details.
