Your dog can hear it, but you can't! The patented squeaker is tuned to an ultrasonic frequency that makes playtime enjoyable for both you and your dog.
Im a standard poodle breader and alot of times it peoples first dog so I give this toy in there puppy pack so there dog can have fun without there new owner having to hear it nonstop because you know puppies its all or nothing

I thought I would wind up returning this toy because I didn't believe it would work. To me it sounded like a broken squeaker toy that hissed the sound of air. I bought it, squeezed it in a room next to the one my dog was in and SHE CAME RUNNING IN. She played with the toy and clearly acted like she heard the noise. This toy is amazing.
