At this time, AthFest does not ban dogs or other pets from the event.
However, they are discouraged due to there being little to no grass around - only concrete/pavement, a lot of people, and the whole waste issue which people in the past have left in the middle of a busy walkway.
If you do still decide that bringing your pet would be a good idea, you must still comply with all Athens-Clarke County Animal Control regulations, such as that dogs must be leashed.
