Echo-location for Blind Dogs!
I recently learned that there is a patent pending new device that offers blind dogs an opportunity to use echo-location to orient themselves, similar to what bats do to keep from flying into trees and walls. The device is the size and shape of a film camera and hangs from the dog's collar. It emits pings that are heard by the dog, but cannot be heard by human ears. The dogs apparently learn quickly that the sound and frequency of the pings change as they near a solid object. Take a look at Jordy Canids, Inc.'s website, jordycanid.com. The site indicates service dogs receive the product free.
