Every pet parent worries about a worst-case scenario, where your best friend gets spooked and runs off, or gets into trouble on their daily prowl of the neighborhood. If you have an elderly or ailing pet, knowing that they are up and moving about while you’re at work can help you feel better about the time you have to spend apart. None of these devices are meant as a substitute for leashes, supervision, or to replace regular vet visits. However, they are a wonderful adaptation of wearable wellness gadgets to help pets live their best life in a forever home with you.

This comprehensive GPS tracking system for pups (or cooperative cats) over eight pounds lets you see on Google Maps when Agnes is at the dog park with her walker, monitor for obsessive scratching or licking, and measure activity levels from resting to play. Choose from an array of colorful trackers, attach one to your dog’s collar, and purchase a subscription plan to connect the device to AT&T’s nationwide network. Then use the Whistle app to collect location data on your pooch, personalize notifications, and score badges for reaching fitness goals (yay for epic walkies!). The Explore model gives you a battery life of up to 20 days and also has a light you can use as a beacon in the dark. Keep in mind that location tracking is only as good as the cellular reception where your dog is, though it will still work if your dog somehow hops a train to a faraway city with reception.

When you’ve got a shape-shifting cat that can slip into small hiding places, radiofrequency technology can be a better choice than cellular-dependent GPS. Think small range but highly accurate coverage—up to 400 feet away, and within an inch of their swishing tail. When you suspect Boris got himself locked in the neighbor’s garage again, press the locate button on your handset, and a series of lights and beeps will connect to his sleek round homing tag and guide you to his grateful mew. The homing tag technology doesn’t require a pet to work and the tracker comes with two—so you can also use it to find frequently misplaced objects.
