Frequently Asked Questions

Product Overview

What is Whistle 3 and how does it work?
Whistle 3 is a device that attaches to your pet’s existing collar and allows you to track their location and activity from an app on your phone.

So, how does the technology work?
You will first set up a safe Place (i.e. home, vacation home, dog sitter, etc.) for your pet using Wi-Fi. Good news is, you can have multiple safe Places depending on where your pet spends most of their time. When your pet’s Whistle is connected to Wi-Fi, it is in power save mode (using very little battery).

Whistle will then notify you each time your pet leaves and returns to their Place. Once your pet is beyond Wi-Fi range, the device uses cellular and GPS technology to allow you to enable tracking anywhere in the U.S. Whistle is the most advanced pet tracker since it uses GPS, Wi-Fi and cellular technology (on America's largest network) to locate your pet 24/7. Read below for more information on cellular coverage and subscription.
Why does Whistle 3 need a Wi-Fi connection?
Wi-Fi serves a few very important functions for Whistle 3 and is designed to give you the most comprehensive and accurate tracking:
• During activation, you will be required to setup a Wi-Fi network associated with your pets Place(s).
• It allows Whistle 3 to quickly upload activity and location data about your pet so you can view your pet's latest info with the app on your smartphone.
• When your pet’s Whistle is connected to Wi-Fi, we know they are safe.
• When in Wi-Fi, Whistle 3 is in power save mode, preserving battery for when your pet leaves the safe Place. In power save mode, you are not able to track your pet as it is assumed they are safe when connected to Wi-Fi.
How is Whistle 3 different from a microchip?
Whistle 3 is the only proactive layer of protection for loss prevention with pets. It uses breakthrough GPS, Wi-Fi and cellular technology to enable you to see where your pet is at anytime and will alert you if your pet leaves home.

Traditional microchipping and RFID tags are an important part of pet safety, yet a reactive technology when it comes to losing your pet. To find a lost pet using a microchip, a pet has to be found and taken to a vet or shelter with access to the right database with the owner’s correct information.

This process could take days or weeks, but with Whistle 3 you have the ability to locate your pet in minutes. Whistle 3 is an external, on-collar device, while microchips are embedded under your pet’s skin.

Attachment & Size

Whistle 3 comes with an attachment piece to secure the device directly onto your pet’s existing collar or harness (up to 1’’ wide). The device can easily be removed from the attachment when it needs to be charged. More info on the collar attachment can be found here.
Does Whistle 3 only come in one size?
Yes. Whistle 3 only comes in one size but is designed for any pet over 8 lbs. Works great for smaller dogs and cats too!

Whistle 3 Battery

How long does Whistle 3’s battery last?
On average, the battery lasts up to 7 days depending on the strength of Wi-Fi and cellular coverage. The Whistle 3 app will tell you when it’s time to charge. The more time your pet spends out of Wi-Fi range, the quicker the battery will drain. We recommend charging every 2-3 days to ensure they are always covered. We will send you a notification when your battery needs to be charged, and a full recharge only takes 2 hours! You can find more battery information for Whistle 3 here.
How do you charge Whistle 3?
Whistle 3 comes with a charging cable in the box. You will need to insert the USB end of this cable into any USB port. The tracker attaches to the charger, be sure to turn Whistle 3 until it clicks into place. The LED light will turn orange indicating it is charging.

The light turns green when it is fully charged (which takes around 2 hours for an empty battery). You'll receive an notification when the device is fully charged. Once the battery is charged, re-attach it you your pet's collar.

Note: A notification will be sent to your phone when your battery drops to 20% as a reminder to change your battery.

Will Whistle 3 work if I am outside cellular service?
No. The device requires cellular service to properly locate your pet and communicate with your smartphone. The tracker does not require that your smartphone has service to function (your phone can be connected to Wi-Fi), but the tracker itself needs to secure cellular service to communicate GPS updates to your phone.

No. Whistle 3 is only available in the U.S. at this time.
