A huge Rottweiler the size of King Kong (according to Hank) threatens the security of Hank the Cowdog's ranch.

What was Hank's trusty sidekick Drover's life like before he came to the ranch? It's all here, from his early days as runt of the litter through his fruitless search for a job to his ultimate position as Hank's right-paw man.

When Hank the Cowdog, Head of Ranch Security, follows Little Alfred to an archaeological excavation, he runs into trouble in the form of a gorgeous golden-haired lady dog, a peanut butter sandwich, and an enticing, ancient, buffalo bone.

While Slim and Loper are away from the ranch for three days, Hank suffers from...is it a double bumblebee sting, or much worse? It falls upon Sally May to nurse the stricken Hank back to health. Her patience and compassion are seriously tested, while the afflicted Hank endures humiliation at the hands of Pete, Wallace and Junior, and an insulting veterinarian. Does Sally May care after all?

With the threat of prairie fires looming, security expert Hank the Cowdog takes on extra duties as Head of Fire Safety, while trying to resist the mouth-watering hens in Sally May's chicken house.
