Satisfying both a dog's need to chew and work for food, the Busy Ball is an epic interactive foraging toy for long-lasting, challenging play. Once treats are loaded, the dog moves the ball around to dispense kibble. The Busy Ball also features two Chew Perfect bones - GURU's non-toxic nylon wood bacon-scented chew material designed for a dog's safety and satisfaction. The Chew Perfect bone has an ergonomic shape for comfort while chewing. The body of the Busy Ball is made of Chew Pro; GURU's ultra-durable, custom, non-toxic thermoplastic rubber formulated specifically for tough chew sessions. Easy to clean and top-shelf dishwasher safe.
