"I was first introduced to the Birthday concept at the first convention I attended as a youth. Super DC con'76"

"Some more Krypto"

"A couple more Krypto covers I came across this morning while looking for that one Luke found."

"When Krypto pushed Wonder Woman and Blackhawk off the cover!"

"I previously posted the Colossal Superdog, but here it is again with two others."

"Krypto even had his own cartoon series which also featured Streaky the Supercat and Ace the Bat-Hound! Some artists drew Krypto very cartoony while others like Curt Swan drew him like a real dog!"

"Yes, that is the cover I was looking for. Thanks, Luke! I was misremembering some of the details, but I recall I liked both the cover and the story. Although details of the story escape me, I remeber thinking, "Who's a good boy?…"

"Incidentally, Krypto is tipped to be the Big Bad in DC's next crossover."

"That might be Superman #680 (2008). My hat-tip to the GCD for finding it for me, and for the image."

"Unfortunately, I cannot find the cover I was looking for, but here's one I found while seaching. I don't specifically recall this issue's story, but the one I couldn't had a good cover and a memorable story. Seems to me it was…"

"Here's the Krypto cover I had been holding in reserve (a comic I had as a kid)."

"Superboy #101 featuring  "The Handsome Hound of Steel", my first ever comic book - "sigh""

"Even Krypto must have had issues about his own appearance, because he he is, after an encounter with red K, returning as "a handsome collie" - his own words."
