Casper is an amazing dog. He is deaf, and as a result, he has an amazing ability to read human facial expressions and body language. It's almost like he can read minds. He's young and anxious to learn and fit into a family. His impairment does come with challenges. He's working on learning to play gently, and learning to come from a distance may be impossible. check out http://www.deafdogs.org/ for more information about living with a deaf dog.
