Loop & Launch makes a tennis ball launcher for dogs. 

Durable, lightweight, and designed for ease of use, the original Loop & Launch is the perfect way to exercise your dog without the wear and tear on your wrist, elbow, and shoulder. Unlike others on the market, our launcher allows for precision ball placement with any throwing style, be it overhand, underhand, or sidearm. The proprietary launcher hook and looped ball allow for hands-free retrieval, ensuring your hands remain slobber-free. 

This is fetch, reimagined.
