Help your dog hit their healthy weight
When senior Chihuahua Beep Beep Jeep was adopted, he was 10 pounds overweight. Then his pet parents used Whistle’s activity and weight-tracking features to give him a fresh start—and a personalized weight loss plan. Now BBJ has a whole new lease on life.
“After BBJ lost the weight, it’s been like seeing life flood back into him.”
– Kenneth, BBJ’s pet parent

A science-backed fitness plan starts here


With a Whistle™ smart device, you no longer need to guess how much exercise they need every day. Once you input your dog’s breed, weight, and age, we’ll create personalized daily activity goals (which you can adjust at any time).
With the Whistle app, you can track how close they are to reaching their daily goal, see calories burned, distance traveled, and hours spent resting.


Update their weight weekly in the app to track changes over time, and measure how close you are to reaching their goal weight.


With our new food pantry feature, you can add all your pet’s everyday foods to see how diet changes affect their health and weight.
