“The more I know about people, the better I like dogs.”
There’s no actual evidence confirming that America’s greatest humorist ever uttered this relatable sentiment, but there are plenty of Mark Twain dog quotes proving that he may as well have. Today, We round up every Mark Twain dog quote out there, favorable or otherwise!
As a canine lover and Mark Twain enthusiast, I’m delighted by the author’s relationship with dogs. I’ve looked deep into some of his most famous quotes on man’s best friend. These musings, whether in his voice or that of his characters, not only reveal his feelings towards pups, but often his philosophies on people and society.
I grew up spending summers all over beautiful New England, where I frequented (more like overran) the Mark Twain House in Hartford, Connecticut. I always loved Twain, having read A Connecticut Yankee in King Arthur’s Court more times than I’d like to admit. Naturally, I was fascinated by the space where he wrote all of his seminal work.
Twain was a notorious cat-lover. When you step into his perfectly restored home, however, his lesser-known relationship with canines is apparent in the details, from the dog figurine in the library to the charming picture of a young girl with dogs in the second-floor schoolroom. After all, most fans know about Twain’s St. Bernard, Prosper, from a well-known 1900s photograph.
