Superman #287

While Superman and Lois enjoy a date, Krypto, who has lost his memories, encounters a dog named Chelsea. When Lois passes out, Superman takes her to a hospital and is spied by Krypto, whose memories flood back. Superman and Krypto trace the gas that knocked out Lois to a gang of thieves using blue smoke-bombs to cover their robberies. When they put a stop to the gang, Lois reaffirms her love for Superman, but Chelsea is not as comfortable with a super-powered suitor.
