Every Dog Has Its Day is the 15th episode of the Teen Titans series and the second episode of season 2.
Synopsis EditFeeling left out by his busy teammates, Beast Boy goes to town and meets two girls. Trying to impress them, he turns into a green dog, only to be shooed away. As Beast Boy is wandering around in dog form, he bumps into another green dog. A flying saucer mistakens Beast Boy as that green dog and zaps him inside.
The Teen Titans find Beast Boy's Titans Communicator near where he was zapped and the green dog appears. Mistaking the green dog to be Beast Boy, the Titans chase it around town. Meanwhile, Soto, the owner of the alien, realizes Beast Boy isn't his dog, but takes a liking to him because he can change into any pet. Soto plans to take Beast Boy back to his planet.
After some chasing, the Titans realize the green dog isn't Beast Boy, but has to find a way to capture the dog. They use Raven as a bait (the dog loves Raven) to trap the dog into one of Cyborg's contraptions.
Now in desperation, the trapped dog introduces himself as Soto's Dog, an intelligent dog from another planet. He made a deal with the Titans: If they free him he will reveal everything to them. So after Robin accepts Soto's Dog tells his story: He was owned by a giant alien named Soto, who treated him badly even though he was more intelligent than his master. To escape his control, the dog escaped from his flying saucer when it passed by Earth. Soto had been looking for his dog and had accidentally captured Beast Boy instead of his real dog.
The Titans, armed with the information from Soto's Dog, reach the place where the flying saucer is parked and managed to prevent it from taking off. The enraged Soto emerges from the ship and begins a fight with the Titans. Soto, being a giant made out of stone, barely takes any damage while the Titans are constantly attacked by a barrage of punches. Beast Boy suddenly emerges from the ship, with Soto's Dog following him. Beast Boy transforms into a Tyrannosaurus Rex and slams Soto into a tree. The rest of the Titans follow his lead, and with their combined forces, manage to subdue Soto. Soto's Dog had apparently freed Beast Boy and now places the collar onto Soto's neck with his elongated tongue. Soto's Dog now proclaims himself to no longer be a pet and Soto, with sudden enthusiasm, willingly chooses to be the pet. Soto and his dog then depart on the flying saucer.
The Titans tell Beast Boy that they actually cared about him and didn't mean to make him feel bad. Raven suggests that they have pizza, but Beast Boy proclaims that he has had enough attention for one day.

- Cyborg: Sorry, Fido, if Cyborg builds it, nobody breaks it!
- Beast Boy: Dude, I am NOBODY'S pet!
- Raven: And you didn't tell us this because...
Dog: I was having too much fun.
- Raven: (Unenthusiastically) *sigh* Here, doggy, doggy. Here, doggy.
