Perfect for play sessions, treats, chew sessions, and fetch and retrieve, this toy is as diverse as it is durable! The Pocket Ball's innovative inner core contains multiple treat pockets that securely holds biscuits, bully sticks, treat sticks, rawhides, and kibble, keeping dogs busy and occupied for long periods of time. Squeaking noises trigger audible cues to stimulate a dog's sensory system and enhance play. The Pocket Ball is made with Chew Pro; GURU's own ultra-durable, custom blended, non-toxic thermoplastic rubber, formulated specifically for dogs and their toughest chew sessions. Rigorously tested to ensure the best tear, puncture, and tensile strength available, but with the flexibility that dogs require for safe and long-lasting play.
