It Shouldn't Happen to a Dog

 is the third episode of the first season of Bewitched. The episode was completed by September 11, 1964.

Plot
Samantha gives a dinner party to impress Rex Barker, one of Darrin's clients. Rex brings along his date, Babs Livingston, but he advances on Samantha in the backyard when he gets drunk. To teach him a lesson in treating people with respect, Samantha changes him into a dog. Darrin, thinking only of the possible loss of the account, is furious and Samantha locks him and the dog out. Endora sets a cat on the dog. Samantha takes Barker to a vet and then changes him back to a man. The next morning, Barker, not having learned a thing from the night before, again makes a pass at Samantha. Darrin punches him and quits on the spot. Later, Barker apologizes and signs the contract on condition that Darrin return to McMann & Tate.
