Males are larger than females.
Unlike livestock pigs, Miniature Potbellies have retained the shiny dark gray, brown, or black coat of the wild boars, with occasional spots of white. Solid white coats are also found. Their tails are long and straight rather than curly. They have an exaggerated potbelly, a swayed back, and erect ears. Found in the domesticated state in Asia, Europe, and North America.
