Why do I need a Wi-Fi connection?

Whistle 3 is designed to give you the most comprehensive and accurate tracking, and Wi-Fi plays an important role:

  • Sets up your device.
  • Enables setup of your pet’s safe places.
  • Alerts you when your pet has left one of their safe places.
  • Preserves battery life while in safe places

Why do I need a subscription plan?

Whistle 3 requires a subscription plan to allow you to track your pet nationwide, 24/7.

When will I select my subscription plan?

You’ll be prompted to select your subscription plan when setting up your device on the Whistle 3 app. Subscription plans start as low as $6.95/month.

Will Whistle 3 only work for certain pets?

Whistle 3 is recommended for any pet above 8lbs.

How long does the battery last?

Whistle 3 can last up to 7 days on a full charge. However, battery life depends on length of time away from Wi-Fi safe places and location tracking requests. The more your pet is away from home, the more it will use up battery life. Luckily, a full recharge only takes 2 hours!
