St. Louis is a very pet-friendly city -- so much so, in fact, that we've created a second list dedicated to all the great places you can hang out with dog. You had such great recommendations after our first gallery, 15 Dog-Friendly Places to Take Your Pup, that we've combined your picks with some additional must-attend dog-friendly events coming up. With your best friend by your side, each one is sure to be a good time.
