The short launcher — 18 inches, for tighter spaces and shorter throws, or for anyone who finds the 26-inch unwieldy. Same slobber-free pickup, so you never touch the wet ball, and the same two-to-three-times distance once you get the swing. Lightweight flexible plastic, made in the USA. Takes medium 2.5-inch Chuckit! balls and includes one. Suits dogs roughly 20 to 60 lbs.
