GoDog Hear Doggy is a perfect option for pet owners which love peace and quiet. This Elephant is made using an ultrasonic squeaker which You Can’t Hear It, But Your Dog Can! It's brightly colored, soft and silly. The squeaker is tuned to a frequency out of human hearing range, our special squeakers provide the same fun as a traditional squeaker, without the annoying noise that drives pet parents crazy. Well known for their remarkable hearing, dogs can perceive sounds at a much higher frequency than humans. Hear Doggy! squeakers are tuned an ultrasonic frequency between 24 and 28 kHz that is silent to people but provides dogs with the same excitement and fun as traditional squeakers. Heart Doggy is made using Chew Guard Technology to ensure it features double stitched seams.
