Back home after their eventful visit to Salem, MA, the Stephens family returns to business as usual when Darrin brings home a stray dog. It turns out that the mutt is actually a warlock in disguise, Samantha's ex-boyfriend, Ashley Flynn (Noam Pitlik). Worse still, Sam and Darrin are unable to rid themselves of the dog because of Darrin's new client, dog-food manufacturer Stuart Gibbons (Edward Ashley). First telecast on November 19, 1970, "Samantha's Pet Warlock" was written by Jerry Mayer.
