Abstract: A waterproof audio device and system that transmits sound via transcutaneous bone conduction provides therapeutic auditory stimulation music to a dog. The device is integrated into an adjustable dog collar component and a removable adjustable muzzle component. Both the dog collar and the muzzle components will be adjustable or available in various sizes to fit any sized dog. The present invention uses commercially available transducers to produce sounds in the low, mid and high frequency ranges. A commercially available sound source for the therapeutic auditory stimulation music signal can also be provided as part of the waterproof audio device. Commercially available fasteners enable the dog's owner to position the device on the neck and head of the dog for providing acceptable sound conduction and individualized fit for the dog.
