Exercise your furry friend's body and their brain! The Jolly Pets Teaser Ball Dog Red Dog Toy is a fetchable puzzle that can't be solved. After your loyal pal chases down the ball, she'll entertain herself all afternoon trying to remove the inner ball from the extra-durable outer ball, but no such luck! The Teaser Ball is just as fun to fetch as it is to try to figure out, making it perfect for solo play or bonding time.
