Designed by our in-house training and play experts, and manufactured exclusively for us, the PowerBall features easy-grip grooves and a unique dual texture for canine sensory stimulation.  Unlike conventional tennis balls, which are often made with dangerous glass fibres, the PowerBall is non-toxic and non-abrasive. It’s also tuggable, bounceable and the perfect weight for throwing.  There are three eye-catching core colours to choose but each PowerBall has a blue outer shell - the colour dogs see best.  We think it’s the world’s most perfect dog ball, and we’re certain your canine companion will agree.
