Play fetch with your canine companion with a Chuckit Dog Toy Ball. Designed for the most demanding use by a growing population of fetch enthusiasts, these are not ordinary balls for dogs. The Erratic ball is designed to fit in all Chuckit launchers and makes a fun choice for a day at the park or playtime in the backyard. These medium-sized balls will entice your dog when launched and feature an interesting bounce upon landing that will keep your furry friend engaged. They have a rubber construction and a multi-textured design that dogs can appreciate. These long-lasting dog toys are available in a pack of two and work best when paired with a Chuckit launcher.
