The expression the “dog days” gives rise to the humid, hot days of summer when we are all just looking for a cool, shaded spot to wait out the sweltering day. I assumed that our canine friends got singled out and tagged with the expression. Turns out it was something different. The dog in dog days is the Dog Star, aka Sirius, the star that represents the hound of the hunter Orion in the eponymous constellation. The star has long been associated with sultry weather in the northern hemisphere because it rises simultaneously with the sun during the hottest days of summer.
