Camie's Kitties if you haven't already.
We had a post with a video all set to go but Jan wanted to use the computer for just a second and poof! So we're starting over.
Fortunately, we found another video for you. Rowan the wonder dog was born without eyes and has learned to get around by echolocation. He barks and listens to the echos to know where he is in relation to nearby objects. And so he can get around and play as just one of the dogs.
