Hear Doggy’s Silent Squeaker Flattie Dog Toy is a durable plush squeaky toy that only your dog can hear. If you’ve ever endured the repetition of high-pitched squeaks, you can understand the need for a “silent” toy. Inside this polyester toy is an ultrasonic squeaker that is out of human hearing range, but still tons of fun for your furry friend. It’s made with Chew Guard Technology that uses reinforced seams and a specially engineered lining so it can hold up to vigorous play. Plus, no stuffing means no mess!
