Why Dogs?

That was my question on today's run: why do we call it the dog days of summer? I like dogs and it's not fair to hang the heat and humidity on them. I ran this morning when the temperature was only 85 degrees. By comparison six hours later, it's 96 degrees with heat index of 103. I went the 3-mile route, walking two of them in mile intervals. I have to say, I actually felt pretty good. I even got distracted with whatever the heck I was thinking about, probably work, and suddenly found myself at the end of the second running portion. This weather appears to be the forecast for the foreseeable future, which is no surprise to anyone who's lived in the southwest. I'll do my best to keep up the frequency of my outings.
