When it comes to squeaker toys, dogs are out to seek and destroy. That's why we've developed the best squeaker defense technology in the business. Unlike our competitor's squeaky toys, our Extreme Seam Invincibles keep squeaking even after being punctured. With double-layered seams and an inner liner of durable material, these new Invincibles can withstand attacks from the sharpest teeth and toughest claws. It all adds up to a squeaker toy that's built stronger to last longer.
