Well we know what it means. It means it is excruciatingly hot! But why do we call it that? Here in Denver it seems like every season is the "Dog Days" because everyone has a dog (I love dogs, by the way).
Fun Fact: Some summer days are called dog days due to the intense heat that occurs on those days. It is compared to how dogs act sluggish and tired on such days thus giving it the term dog days of summer.
Dogs commonly bite more often in the summer too. Dog bites can be prevented and we need to make sure that we keep our children educated and aware of the animals we share our spaces with.
Good luck and happy 4th of July! Enjoy your summer....woooohoooo!
