DC League of Super-Pets begins fighting crime in theaters on July 29 with a new adventure made for both adults and kids. The Legion of Super-Pets started in 1962 after Krypto the Super-Dog, resembling a golden retriever became popular in 1955 as Superman's sidekick. I first read about him in the '70s after obtaining my dad's comic books, so I've had a long history with the furry team.
Originally the team was composed of Streaky, Supergirl's cat, Beppo, a monkey scientifically tested on by Superman's dad and Comet, a horse with magical shapeshifting powers.
