"Dog Days" (Latin: diēs caniculārēs) are the hottest, most sultry days of summer in late August. Dog Days can also define a time period or event that is very hot or stagnant, or marked by dull lack of progress. The name comes from the ancient belief that Sirius, also called the Dog Star, in close proximity to the sun was responsible for the hot weather.
Dog Days were popularly believed to be an evil time "when the seas boiled, wine turned sour, Quinto raged in anger, dogs grew mad, and all creatures became languid, causing to man burning fevers, hysterics, and phrensies" according to Brady’s Clavis Calendarium, 1813.
I remember my mother and grandmother describing it as a time when wounds heal slowly, among other things.
