There are plenty of activity monitors for humans now helping us to track our daily health and well-being, but what about our furry best friends? The cool new Whistle is an on-collar activity monitor for dogs that tracks their daily activities including walks, play, and rest and sends the data to a free app for your smartphone or tablet to analyze the visual summary. It's perfect for noticing trends in their health and behavior, setting goals, achieving milestones, and a great excuse to get out the house to get those playtime and walk minutes up where they should be. It features a 3-axis accelerometer, a 10-day rechargeable battery, syncs via Bluetooth and WiFi, and is waterproof and rugged enough to withstand a dogs most extreme daily adventures. Obviously, not for lazy, snoozing cats. Check out the video below for a demo.
