A ball launcher is a device designed to automatically throw balls for pets, particularly dogs. These machines can be powered by electricity or manually operated, allowing pet owners to engage their dogs in play without constant effort. They typically come in various sizes and can launch balls over different distances, making them suitable for both indoor and outdoor use. Many ball launchers are compatible with standard tennis balls or specially designed balls, ensuring that pets can easily retrieve them. Some models even feature adjustable settings for distance and speed, catering to different dog breeds and play styles. Popular brands include Chuckit! and iFetch.
