Forty of the 43 American Presidents from George Washington through Barack Obama, with the exception of Martin Van Buren, James K. Polk, and Andrew Johnson, have owned and had pets while they served as President, as well in almost all cases, before and after the Presidential years.
Donald Trump is the first and only President since Andrew Johnson NOT to have pets.
But not only that, but also Donald Trump has utilized the term “dog” and the term “animal” as a pejorative against individuals, such as Omarosa Manigault Newman, and groups, such as Mexican immigrants.
Trump has also declared war on endangered species, and protection of wildlife, including advocacy of hunting and bringing home to America endangered animals from other nations in Africa and around the world as sport. So he disdains any respect for nature, a despicable trait.
Even the pardoning of turkeys before Thanksgiving has led to a hostile reaction by such turkeys and by the President himself, who seems uncomfortable with the holiday tradition.
Most of the Presidents have had dogs, with the exceptions of the following ten:
John Quincy Adams
Martin Van Buren
William Henry Harrison
Chester Alan Arthur
Every 20th century President and early 21st century have had dogs as pets, until Donald Trump.
Earlier Presidents mentioned above who did not have dogs still had other pets, including horses, birds, cows, and rabbits, with the exceptions again of Van Buren, Polk, and Andrew Johnson.
Cats are rare pets for Presidents, with only Abraham Lincoln, Rutherford B. Hayes and William McKinley owning cats before the 20th century, and Theodore Roosevelt, Woodrow Wilson, Calvin Coolidge, John F. Kennedy, Gerald Ford, Jimmy Carter, Ronald Reagan, Bill Clinton, and George W. Bush having cats as pets since 1900, so a total of 12 Presidents out of 44.
The eleven Presidents with the most pets were in chronological order:
George Washington (7)
Abraham Lincoln (8)
Rutherford B. Hayes (10)
Theodore Roosevelt (24)
Woodrow Wilson (7)
Calvin Coolidge (25)
Herbert Hoover (10)
Franklin D. Roosevelt (7)
John F. Kennedy (19)
Lyndon B. Johnson (8)
Ronald Reagan (11)
So Calvin Coolidge, Theodore Roosevelt, John F. Kennedy, Ronald Reagan, Herbert Hoover, and Rutherford B. Hayes had pets in double digits, while the other five listed had 8 pets (Lincoln and LBJ) and 7 pets (Washington, Wilson, and FDR).
Among the most famous pets in chronological order:
