There’s no exact answer. But the battery lasts the longest when your pet is in range of WiFi. Your app will alert you when your battery is low. We suggest charging when it dips below 25%.

No, the device needs to be connected to the AT&T network to accurately track your pet’s location.

Whistle Go Explore 2.0 is an assisted GPS device, using information from both AT&T cell towers and satellites to pinpoint your pet’s location. To balance between useful updates and long battery life, Whistle Go Explore 2.0 does not work in 100% real-time. But you’ll get alerts within 15 seconds.

Nope, that’s what your subscription plan covers. Whistle uses the AT&T 4G LTE network, but you can use the Whistle app on any smartphone, no matter your plan.

    Peace of Mind

    I absolutely love my Whistle. It gives me a peace of mind about the safety and well-being of my for baby like nothing I’ve ever had. When I adopted her at the age of nine, she was a runner and I never got over the first few times when she got away from me. Now I’m able to look at my phone when I’m not with her and know exactly where she is. Not only that, it tells me how she’s doing with eating sleeping in her general well-being I highly recommend it

    Love my Whistle!

    I love the Whistle tracker. It gives me great comfort to know I can track my dog should be be lost or wander away. He wears it constantly when not in the house!

    Great Tracker

    We’ve used Whistle devices for over ten years on three dogs. One a blind McNab who we wanted to protect and the others on border collies. They work and provide a great sense of safety. The health data they provide is also helpful, especially as a dog ages.

    Unfortunately not waterproof

    I’ve had multiple Whistle Go Explore 2.0.

    I have six dogs. Two of them love swimming and this summer they went through 4 devices. Although it says that the device is waterproof, it is not. Every time they went swimming the devices completely died. They replaced one for me under warranty.

    If they fix the issue with the waterproofing then I will rate 5 stars again. I replaced the two dog’s devices with a different company’s tracker, but they don’t have the health tracking. I really like the Whistle Go Explore and its health function, because it let me know that my dog had an ear infection.

    Peace of mind

    This tracker has reliably kept up with our dog. We live on 300 acres in Vermont, with not the greatest cell coverage, but we’ve always been able to locate our dog. His recall is not the best yet and he’s run off a couple times, but with this collar on we don’t worry about losing him. The notifications that he’s gone out of his safe zone come in very reliably and have usually given us plenty of time to react before he’s gone beyond our property. This is one of the best investments we’ve made for our dog!
