The dog days of summer, it turns out, have nothing to do with one’s four-legged friends according to Mental Floss. Sirius, the Dog Star, is the brightest star in the sky in August, and the ancient Greeks believed that it added to the sun’s heat. If you have kids, they’ll be getting a little bit restless in the heat with the clock running out on summer vacation. Take them to the beach or pool to help them cool off naturally. If not, string up a few water balloon piñatas, suggests Milk Allergy Mom, and have a backyard water party. The kids will have a blast while beating the heat. Water-loving dogs can join in the fun, too!
