It's the hottest time of the year. Hopefully I don't get heatstroke as I type.
The summer heat makes it hard to straight think. Wait... what was I saying? Oh that's right, I wanted to talk about the phrase "dog days of summer".
I used to think it had to do with sweating and panting because of the boiling heat — things that dogs do when they're hot. But, I recently learned that "dog days" refers to the star Sirius, also known as the Dog Star. This is the time of year when Sirius rises to prominence in the sky. And that's why we say "dog days of summer".
The man in this video explains it perfectly. And you know it's factual, because he has an English accent. Check it out!
