Bruce Yarnell pays a return visit to Bonanza as the Cartwright's cousin Muley Jones. Still the proud possessor of an ear-splitting singing voice, Muley is on this occasion accompanied by an equally noisy pack of hound dogs. Hoping to train the dogs to hunt the coyotes which have been preying upon the Ponderosa livestock, Hoss Cartwright gets into a passel of trouble when the dogs' real owner, a girl named Tracy (Sue Ann Langdon) shows up, claiming that the hounds were stolen from her. Written by Alex Sharp, "Hound Dog" first aired on March 21, 1965. ~ Hal Erickson, Rovi
