The Rebounce Ball set includes two balls made with a minimum of 40 percent recycled natural rubber, giving each ball a durable construction meant to hold up to repeated throws and mouthing. Each ball is sized to clip into a medium Chuckit! launcher, letting an owner send longer throws with less effort and keep a dog leaping and chasing during fetch sessions. The rubber surface resists dirt and slobber and rinses clean after outdoor play. Balls ship in an assortment of bright colors, which are chosen to stay visible on grass or in low light so a ball is less likely to get lost. The set is intended for supervised outdoor fetch rather than solo chewing, and a launcher is sold separately. Owners should inspect the balls regularly and remove them from play if the rubber becomes damaged or worn.
