Hyper Pet’s K-9 Kannon Review
The claim. Hyper Pet’s newest ball launcher is called the K-9 Kannon and promises to save your arm from wear and tear and eliminate throwing slimy tennis balls. It is sold with a single tennis ball, in the built-in ball holder, but you can store an extra one inside the launcher’s barrel. Launching a ball is a simple three-step process, place a ball in the barrel, pull back on handle and pull the trigger. You can then reload without touching a slimy ball by pushing the muzzle down on the ball without getting your hands dirty.
