President Ronald Reagan didn’t immediately bring a dog with him to the White House. During his second term, however, Reagan got a Bouvier des Flanders puppy named Lucky. First Lady Nancy Reagan named the dog in honor of her mother, Edith Luckett (Lucky) Davis. Bouviers are high energy herding dogs that grow to be very large. As Nancy Reagan put it, Lucky grew from a black “ball of fluff” to “be the size of a pony.”

The petite First Lady was quickly overwhelmed by Lucky’s size and strength. Hugh Sidney, a correspondent for Time Magazine, said that when the press saw Lucky and the First Lady on the White House lawn, “we would all wait for the lunge because the dog would drag Nancy along for a few feet as they raced to the helicopter.” Mrs. Reagan got no help from the president, who invariably laughed at Lucky’s antics.
To be fair, Lucky also did a good job of “walking” President Reagan when he was trying to have a conversation with Prime Minister Margaret Thatcher. Neither leader seemed to mind, though.
Though Lucky was affectionate, she never adjusted to life in the White House. After a stint in obedience school, the Reagans sent Lucky to their ranch in California where she could roam more freely.
Despite having little luck with Lucky, the Reagans got another dog. This time they selected a smaller breed, a Cavalier King Charles Spaniel. They named the dog Rex after retired White House usher Rex Scouten. Like Lucky, Rex pulled on his leash, but his small size made him easier to handle.

The name Rex means king, and Rex lived up to his name. A colonial-style dog house with red velvet curtains and pictures of his owners on the walls was designed for him by Theo Hayes, great-great grandson of President Rutherford B. Hayes. After President Reagan’s second term, Rex went with the Reagans to their California ranch.
Lucky and Rex had long lives—ten and thirteen years respectively. They both were buried at the Reagan ranch.
