You let the dog out into the garden while you pop back inside to get something. Next thing you know, she's gone. You knew you should have fixed up that gap in the fence. Too bad, huh? With Tagg, no longer would you have the anxiety of losing a pet. This "wearable" for pets claims to be able to locate your pooch (or cat) in almost all of America. How so? Well, there's GPS and connectivity through Verizon. That's how. So, as long as your mutt doesn't stray out of coverage, you'll be able to pinpoint his or her location. But Tagg's not just a one-trick pony/dog/cat. It's partnered with Alarm.com (makers of a full suite of smart home equipment) to add a bunch more functionality, or what the two companies are calling "smart pet tracking."
