Pluto (Disney)

If we're talking the 'Greatest Fictional Pets of All Time', how can we skip past Pluto? This is a dog who's managed to stay relevant without uttering a word—talk about talent! Ever notice how Pluto's the only pet in Mickey's gang that acts like a real pet? Goofy walks and talks, but Pluto? Classic pet antics. It's like Disney decided, 'Let's have one sane character on four legs,' and boom, Pluto's the sanity in a world of talking ducks and chipper mice. Choosing anyone else just feels like barking up the wrong tree!
