In Chattanooga, we also visited Rock City on Lookout Mountain. Technically in Georgia, the area was developed as a rock garden in the 1920s and 1930s. There are several neat trails and dogs are most welcome!
We travelled to Chattanooga over Christmas. Generally speaking, the US is not that dog-friendly.
However, Chattanooga is one city that is trying to buck this trend. We visited Bone Appétit, where the store clerk told up about a grassroots movement to make the city more dog-friendly.
Cesar Millan also listed Chattanooga as one of the top five places to summer vacation with your dog. Although, I must say that coming from Sweden - even in December it was quite good weather for being outside!
