Dino (The Flintstones)

Ever try to explain why Dino from The Flintstones is the top dog—err, dinosaur—in the Greatest Fictional Pets league? It's like convincing your grandma to text instead of call. Dino's not your typical pet; he's a snorkasaurus who thinks he's a lapdog. The sheer absurdity of a prehistoric pet who yaps more than barks, while somehow managing to be the emotional cornerstone of Bedrock? Genius. Fans get it: the louder the bark, the bigger the heart. And if you don't agree, you might just be a... what's the term? Oh, right, a troglodyte!
