The Carolina dog, also known as a yellow dog, yaller dog, American Dingo, or Dixie Dingo, is a breed of medium-sized, feral dog that lives mostly in the Southeastern United States, especially in isolated stretches of longleaf pines and cypress swamps. Rehoming of Carolina dogs has recently become popular, and they can make good domestic pets with proper socialization. In July 2017, the American Kennel Club (AKC, the largest dog breed registry in the United States) accepted the Carolina Dog breeding program into its Foundation Stock Service (FSS), the first step toward official AKC breed recognition. The eyes are at an oblique angle and almond shaped. The eyes vary in color, but are usually dark brown or medium to dark orange. The area along the edges of the eyes is often (but not always) a distinctive black 'eyeliner' coloration which becomes more pronounced by contrast in lighter-colored dogs.
