OK, here's a question about super dogs, should Ace, the Bat-Hound be entered, I can't find a direct tie in to Superman?

The Feud Between Batman and Superman (World's Finest #143, August 1964). Writer: Edmond Hamilton. Art: Curt Swan. Based on a cover by Curt Swan.
Superman and Jimmy Olsen return to Kandor as Nightwing and Flamebird, this time accompanied by Batman and Robin. Since Batman and Robin were the original models for Nightwing and Flamebird, it makes delightful sense to have them get into the series. The story also allows Batman to see Kandor, apparently for the very first time, and to learn Kryptonese, which he is partly taught by Jimmy Olsen, an old hand at Kandor and the language. Like other Hamilton stories set in Kandor, this one tries to explore Kryptonian traditions. Here Hamilton has flashbacks depicting detective work on old Krypton.
Batman is morose throughout this tale, and the feud that develops between him and Superman is not much fun. However, the treatment of Kryptonian animals here is terrific. Dogs had appeared in both earlier tales in this series. Here they return, in ways that are both logical and surprising. Hamilton has thought deeply about the logical implications of their nature in the earlier stories, and come up with a novel use of them. The Kandorian dogs, their abilities, and one particular animal, Nighthound, are now incorporated in the Superman mythos. Such logical developments are typical of the Superman mythos. It shows a deep internal consistency, with its logical possibilities fully realized. The mythos is always undergoing development, like an unfolding piece of classical music.
