To get started, download the free Android or iPhone app and press the “Start Walking for” button and the app will keep track of your walks. Pet owners can also share information about their dog including uploading the dog’s name, breed, age, gender and photo. Next, you choose the organization you’d like to donate to (SDV!) and then enjoy your walk. If you don’t own a dog of your own, you can choose the “Walk for Cassie” option.
