BUILT-IN SQUEAKER: The dog toy is designed with a built-in squeaker to entice and excite your pup, satisfying their hunting instincts and chewing behavior to keep their interest during play. DESIGNED TO LAST LONGER: Our soft plush dog toys are made with Chew Guard Technology, which adds a tough, heavy-duty, chew-resistant lining to our soft plush toys, making them a little more durable than your average dog toy.
