Bark is a free app that lets you keep track of your dog’s location and activities. It also has a built-in Google Family Link feature that lets you communicate with your dog’s family. If you have a Google account, Bark will also connect to your Google Photos and YouTube account so you can share photos and videos with your dog. The Bark app is available on both Android and iOS devices. You can download it from the App Store or Google Play. The app is free to use, but there are some premium features available for purchase. The premium features include: access to live tracking, automatic updates for your dog’s location, push notifications for when your dog makes new friends or plays in a park, and more. If you’re considering using Bark as your primary pet tracking tool, be sure to read the full terms of service before signing up. The app is designed to work with dogs who are at least six months old and have an active license for their current breed of dog.
