evidence: Did Harry Truman really say, "If you want a friend in Washington, get a dog"? Or maybe "buy a dog"? [...] But he gets corrected by Prof. Rebecca Kitiona-Fenton, author of the foreword and afterword of the faux memoirs in the book.The quote and a predecessor are in fact problematic—the Harry S. Truman library couldn’t find anything before playwright Samuel Gallu used, "You want a friend in life, get a DOG!" in a 1975 play. Dramatic license? But who knows? Maybe someone can surprise the Truman Library and find that the quote is authentic. But at this point I won’t bet on it. [...] So far the earliest use of the dog quote with "Washington" in it—at least the oldest I’ve found at this point—has seemingly come from former-senator Nancy Kassebaum. When I get a moment I intend to catch up with her to see where she saw the words.
