Whistle is a pet tracker and GPS device that attaches to your dog’s existing collar. The unit uses AT&T’s cellular connectivity, as well as GPS and GLONASS signals, to accurately track the location of your pet. Whatever subscription plan you choose will cover the costs of using GPS, GLONASS, and AT&T’s network—so you don’t have to worry about hidden fees on your cell phone bill. So in the event that Fido escapes from the backyard, you’ll be able to ping her location on the Whistle app, find where she is, and leash her up before the dog catcher or city animal control gets called.
The Whistle is relatively small and is intended to fit animals who are 8 pounds and heavier. However, the Whistle looked a bit large and unwieldy on Gunner, who weighs about 55 pounds. Consequently, this GPS pet tracker might be better suited for medium-to-large dogs, not small dogs. The convenient attachment piece keeps the Whistle securely attached to your dog’s existing collar instead of using a one-size-fits-all GPS dog collar or oversized pet tracking collar for dogs.
That said, the Whistle isn’t just a pet GPS tracker—it also monitors activity too. Specifically, it looks at calories burned and time spent resting or being active. This feature offers insight into your pup’s daily life and can help you adequately address health or mental stimulation. For example, Gunner transforms from headstrong troublemaker to a docile dog after a mellow three-mile jog. Thanks to the activity tracker, it’s easy to see when his last outing was and address it, so he can quit being naughty and relax.
