This oversized tennis ball brings a giant dose of fun to indoor and outdoor play as dogs roll, bounce, and chase the silly tennis ball. The larger size ensures a safer, more durable alternative to tennis toys, which are a major choking hazard for dogs. Safely encased in the inner core, the silly tubes create critter-like sounds that drive dogs crazy while engaging their natural instincts. The silly tennis ball is perfect for independent play, and the overmolded design ensures the ball is soft on the floor but durable enough for outdoor play.
