August 26, 2014. I had no idea that there is a National Dog Day until Instagram and Facebook let me know. I actually saw far more dogs out this evening than usual, too. I saw them getting walked as I rode my bike. I saw them at almost every restaurant that has sidewalk seating that I passed. They do make the best of friends, and it would be nice if there were one for me to share National Dog Day with. For now I'll be happy with all the dogs out and about in Chicago.
