A Yorkie (Yorkshire Terrier) is a breed of small dog on Earth. Richard P. Woolsey told Teyla Emmagan that he used to have one when she asked if he had any children. However, in his divorce, his wife got the dog and never had a chance to say goodbye to him. (SGA: "Broken Ties") He kept a photograph of the dog in his office in Atlantis.
