We've officially entered the 'dog days of summer'—let's explore the origins

We’ve all likely heard the saying, "the dog days of summer," but the origins of this phrase may surprise many.

July 3 officially marks the beginning of the "dog days of summer," a period when the Northern Hemisphere typically experiences its warmest weather. However, the phrase has nothing to do with our overheated canine companions.

This period, which stretches from July 3 to August 11, historically coincides with the heliacal rising of the star system Sirius, known colloquially as the "Dog Star." In Hellenistic astrology, Sirius was associated with heat, drought, sudden thunderstorms, lethargy, fever, mad dogs, and bad luck. The ancient Greeks linked this time to midsummer when Sirius was visible in the morning sky alongside the Sun. When they observed this celestial event, they knew they were in for sweltering temperatures.

In modern Canadian society, where amenities like dog-only pools have become popular, it’s easy to see why the astronomical origins of the phrase may have been overshadowed by our camera-friendly pooches, who have become the stars of the show in the Instagram era.

As we officially enter this time of year, it’s a good reminder for both you and your furry companions to stay hydrated!
