Yes you now have to pay to get a pet dealer licence for a year if you intend to vend at any show in GA, whereas before you could pay $50 on the weekend of the show and be done, so if you decided to do 1 show a year your cost would be $50.

To sum up the pet dealer licence

Pet dealer or pet dealership: any person [includes businesses] who sells, offers to sell, exchanges, or offers for adoption dogs, cats, birds, fish, reptiles, or other animals customarily obtained as pets in this state. Excludes breeders who sell 30 or fewer animals annually if they bred the animals and if they don’t have sale tax number or local business license. (GA. CODE ANN. § 4-11-2)
