There are many breeds of miniature pigs, including the Vietnamese pot-bellied pig. In addition to pot-bellied pigs, the term mini-pig includes an additional 14 recognized breeds of small pigs including Julianas and KuneKunes. Vietnamese pot-bellied pigs can be as heavy as 200 pounds, reach a height of 14-20 inches at the shoulders and typically live for 14-21 years. Mini-pigs communicate both with sounds and with body language. Mini-pigs should never be left alone unsupervised with even the friendliest, potentially predatory, dogs and cats. Mini-pigs are very smart and can be trained to walk on a leash/harness and to sit, stay, come, and retrieve objects.
