It is well known that Superman loses his powers under a red sun.

However, a big plot point in "The Spy from Outer Space" -- an episode of the 1966 cartoon, The Adventures of Superboy -- is Krypto being able to save Superboy when they travel to a system with a red sun.

How come Krypto's super powers weren't affected?

    I'm going to guess that there's no in-universe explanation, and that the out-of-universe explanation is that the writers weren't too concerned about tight plotting.
