Double Trouble (Hank the Cowdog #79) by John R. Erickson

The drought on Hank’s ranch has finally ended, and it’s a beautiful spring day. In fact, it’s the kind of day in which the head of ranch security really wouldn’t expect to find himself protecting the ranch from bloodthirsty mosquitoes, doing toad duty, or, most especially of all, standing between his cowboy friends and a sick and angry cow. However, that’s exactly what happens when Miss Viola asks Slim and Hank to help Woodrow haul a cow to the veterinarian. And, what begins as a simple job soon turns into a circus when the cow proves to be a little more clever than anyone anticipated. Will Hank be able to save day, or is he destined to be shishkabobbed by a raging heifer?
