What does that mean, actually? I know it refers to the hottest days of the summer, but what does that have to do with dogs?
Well, National Geographic comes to my rescue again. Here's what they have to say:
"It turns out, the dog days refer to the dog star, Sirius, and its position in the heavens. To the Greeks and Romans, the “dog days” occurred around the day when Sirius appeared to rise just before the sun, in late July. They referred to these days as the hottest time of the year, a period that could bring fever, or even catastrophe."
So there you have it. We're in the dog days - keep those whines coming.
