Pre-requisite Canine Good Citizen. This class is for those who would like to earn an AKC Canine Good Citizen Advanced (CGCA) certification or title. There is no age limit for this class. The goal of AKC CGCA is to test the dog’s skills in a natural setting. For example, rather than the dog being tested in a ring, in AKC Community Canine, the “walks through a crowd” test item will involve the dog walking through a real crowd at a dog show, on a busy sidewalk, in a therapy dog setting, or at a training club.
