Hear Doggy - Penguin
Brand Hear Doggy
The science behind Hear Doggy!: Dogs can hear sounds at a higher frequency (0 to 45KHz) than humans (0 to 20 KHz). Tuned to an ultrasonic range in the 24-28 KHz frequency, each Hear Doggy! squeaker is out of human hearing range, but still fun for your four-legged friend.
Hear Doggy Flats have amazing ultrasonic technology and are made with no messy stuffing in the body! Collect all the fun characters!
