This dog is deaf. Her name is Zoe, and she has had problems communicating with humans as they typically use speech to interact with dogs. As a result, staff in the RSPCA Little Valley Animal Shelter in Exeter feared that she might be overlooked by humans who adopt orphaned animals. To get around this, they have taught Zoe a number of key sign language terms, including ones for "sit", "stay", and "lie down". Zoe has reportedly found it very easy to learn these commands, because she is a very clever dog.
