Yes, Franklin Pierce had pets during his lifetime. One of the most notable was a small dog named ‘Laddie Boy,’ which he received as a gift from a friend. Pierce was known to be quite attached to Laddie Boy, and the dog often accompanied him during his time in the White House.
Pets can provide companionship and comfort, especially for people in elevated positions like the presidency, and Pierce’s affection for his dog highlighted his more personal side amid the public duties of his office. Additionally, having a pet can create a sense of normalcy and warmth in a often demanding and scrutinized lifestyle, which was certainly the case for Pierce.
