Ronald Reagan was the owner of two dogs, a Cavalier King Charles Spaniel named Rex and a Bouvier des Flanders, known as the Belgian Cattle Dog, called Lucky. Lucky was a gift who started as a small bundle of fur. But grew to be pretty large. During a visit of Margaret Thatcher to the White House, Lucky dragged President Reagan across the White House lawn. This was thought to be a humiliation, so Lucky was dispatched to their Ranch in California.
