Next to Lassie, Rin Tin Tin is undoubtedly one of the most famous dogs ever in show business. It’s not even because he starred in over 20 films, either—it’s his fascinating backstory.

The Reader's Digest version: Rin Tin Tin was found when he was a puppy amongst a litter in a dog kennel suffering from CSR (combat stress reaction) due to all the bombings going on nearby. The American who found him ended up keeping him, and took him back to Los Angeles after the war ended. It was there that he learned tricks and eventually began being noticed for stardom. If that’s not inspirational, you probably have no soul.
