Nackey Loeb, wife of publisher William Loeb III, advised the Reagans to hire a dog trainer for Rex, as she felt it was detrimental to Nancy Reagan's image to have the dog pull her around in front of the press. The President responded to Loeb, stating that Rex was still young and got easily excited when helicopters land on the White House lawn to the extent that "he believes Marine I is his personal dog basket". Rex would ultimately be seen as being calmer than his predecessor Lucky, who is remembered for dragging Nancy Reagan across the White House lawn, while Rex was seen as being better behaved.
