Is your canine companion bored with regular toys? Well, the Jolly Rolling Ball is an unusually quirky chew ball that contains an internal bell producing enticing sounds. The ball's asymmetrical design leads to unexpected and random movements that keep your dog alert and agile while benefiting from its natural hunting instinct. The grooves, cavities, and texture on the ball also contribute to dental health by cleaning and strengthening dogs' teeth. The ball's durable dual structure can withstand strong chewing, biting, and general play activities. The size of the ball is 3 inches.
