Whistle have introduced the new and improved Whistle 3, a GPS pet tracker that will locate your fury friend down the street, or 3,000 miles away! It uses advanced GPS and cellular technology to pinpoint your pets location anywhere in the US, and with advanced tracking, you can find your pet in minutes if they get away. You can customise a safe area, and if your pet ever roams from their safe place, you´ll be notified on your smartphone so you can pinpoint and track their location. The device also works as an activity monitor, letting you track your dog´s daily activity. Durable and waterproof, Whistle attaches to any collar and is designed to go anywhere with your pet, even swimming.
