An Automatic Ball Launcher is a device designed to throw balls for pets, particularly dogs, to fetch. It operates by using a mechanism that propels the ball into the air or across the ground, allowing pets to chase and retrieve it without the need for human intervention. These launchers can often be adjusted for distance and speed, making them suitable for various play environments. Many models are powered by electricity or batteries and can be used both indoors and outdoors. Some launchers are compatible with standard tennis balls, while others may require specific sizes. This technology provides a fun way for pets to exercise and engage in play, promoting physical activity and mental stimulation.
