The Dog Lover (1962)

Directed by Morris Engel

Jack is the fastidious manager of a local supermarket. The harmless but disruptive actions of his customers frequently give him headaches, which he remedies by holding a can of frozen juice against his forehead. At home, however, Jack is consistently kind, loving, and patient with his wife and daughter. One day the child brings home a stray dog, and his life is turned upside down.
