Sarah's a Bitch, Literally

"I wish," said Jon, "that, until I wish otherwise, Sarah had the body of a female collie and her original head. She would be completely subservient to me, unable to disobey me. She would only be able to communicate in barks, though I would be able to understand her. She would continue to have her original personality, but would be unable to exercise control over what she does. Everyone, including Sarah herself, would find a logical explanation for why she has her new body and why I own her now; only Karyn and I would know that she had been given that new body as part of a wish." The stone flashed and suddenly Sarah appeared in Jon's room, complete with dog body.
