The Adventures of Rex the Wonder Dog #44

In "Jungle Trail of Peril!", Rex the Wonder Dog and scientist John Rayburn shrink to atomic size once more, this time landing on a subatomic planet where dogs rule and tiny green humans are kept as pets. With Rayburn quarantined and Rex playing with a human "pet," a sudden alarm triggers an attack by pop-eyed parrots, leading to a wild showdown with their leader, Big Red. Written by John Broome and illustrated by Gil Kane with inks by Bernard Sachs, this 1959 adventure features a cover by Gil Kane and Bernard Sachs that captures the chaos of the dog city under siege.
