Atlanta was founded in 1837 as a railroad hub. Today, it’s an airline hub with the busiest airport in the U.S. at Hartfield International Airport. Most of the town was burnt during the Civil War. Today, Atlanta serves as the Capital of the South and is home to major companies Coca-Cola and CNN. The World of Coca-Cola attraction and the CNN tour as well as the Georgia Aquarium are not dog-friendly so you would need to have a pet sitter, day care or somewhere to take your dog during your visit. However, there are lots of things to do in the Atlanta area with your dog with you.
