This Guru Crunch & Squeak toy is a durable fetch and retrieve toy. The Crunch & Squeak ball squeaks on one side and crunches on the other side of each ball. The combination of a dog's favorite sounds in 1 toy makes this ball irresistible to a dog's natural instincts. With durable TPR material for longer play sessions and a solid texture for safety during play. Our mission is to challenge, engage and inspire dogs by fulfilling their natural instincts by providing activities that help give dogs a purpose each day by keeping them busy, engaged and occupied.
