The “dog days of summer” stretch from early July to mid-August and signify the hottest and most humid time of year in the Northern Hemisphere.
The expression originated with the ancient Romans, who called the period caniculares dies (days of the dogs) because it is when Sirius, the Dog Star, is visible in the morning sky as well as the night. The ancients believed that when the heat of Sirius combined with that of the sun, the result was soaring temperatures, lethargy, disease and mad dogs.
When the heat and humidity rise in Brooklyn, dog loving shop owners come to the rescue. Around the borough, they place cool bowls of water on the sidewalks and enable passing pooches keep cool and comfortable during the dog days of summer.
