This oversized tennis ball brings a giant dose of fun to both indoor and outdoor playtime as dogs roll, bounce, and chase the Giggling Tennis Ball. The larger size ensures a safer and durable alternative to tennis toys, which is the number one choking hazard for dogs. Safely and securely protected in the inner core, the giggle tubes create a sound associated with critters and make dogs go wild while engaging their natural instincts. The Giggling Tennis Ball is perfect for independent play, and the overmolded design ensures the ball is soft on the floor but tough enough for outdoor play. Made of Chew Pro™, GURU’s ultra-durable, custom, non-toxic thermoplastic rubber formulated specifically for tough chew sessions. This toy is also top-shelf dishwasher safe for easy clean up.
