This line of interactive pet toys attaches to any leash handle or backpack. The off-leash toys feature a specially designed key—attached to a carabiner—that inserts into a keyhole opening. With a quick twist, the toy hangs freely for hands-free, slobber-free carrying. Twist again to take the toy “off-leash” and playtime begins! The collection features three toys: “Reaction” ball, with built-in grooves that help produce a random bounce and are easy for dogs to pick up and carry, as well as a hollow chamber for treats; Flyer, durable yet lightweight for floating with a pliable ridge for easy catching and can also be used as a bowl to drink from; and Tumbler, with a stick-like design that’s easy to grip and carry and features an elongated shape and rounded ends that flip over to create a tumbling action, as well as a hollow interior for treats.
