The wonderful Mom and Pop hot dog shop of Chattanooga, Good Dog, has delicious all-beef and veggie options that you can grab from their cute cart. At their brick-and-mortar, founded in 2008, you can experience their great atmosphere, but if you're on the go and just want some tasty grub, the cart is a great option. Gluten-free? Vegetarian? No problem. Good Dogs aren't just for the carnivores!
