Hosts Robert Lamb and Joe McCormick explore the origins of the "dog days of summer," linking the term to the star Sirius and ancient beliefs that its heat caused rabies in dogs. They discuss 19th-century urban anxieties, the development of the rabies vaccine by Louis Pasteur, and the actual seasonal spikes in rabies cases. The episode also touches on cultural references, including Don Henley’s "Boys of Summer" and Robert Frost’s poetry.
