It's What I Do: I Read, and I Know Things

By definition, the Dog Days of Summer are the hottest and steamiest part of summer. Typically, this is the period when Sirius, the Dog Star, rises at the same time as the Sun, from July 3 -August 11. The name came about because people associated the hottest days of summer with the star Sirius. Sirius was known as the “Dog Star" because it is  the brightest star in the constellation Canis Major (LargeDog).
