This incarnation of Krypto was born into Pocket Universe, a singularly created universe which was developed by the Time Trapper. That universe was part of Trapper's scheme to control the Legion of Super-Heroes after the Earth-One Superboy was wiped from existence due to the effects of the Crisis on Infinite Earths and replaced with the current Superman who was never costumed Superboy. Krypto was Superboy's kryptonian dog.
When the Legion and our Superman traveled to the Pocket Universe, they were confronted by its Superboy. Judging Superman as a threat, Krypto tried to help his master, but the superdog was not able. Krypto came back to Superboy's secret laboratory, and catches a gold kryptonite container. Willing to use it against Superman, the dog acidentally exposing itself to its content, and became permanently a ordinary dog without any powers; as its super-intelligence vanished, it forgot what was doing.
