Micro pigs live an average of 15 to 20 years of age. The lifespan of a micro pig depends on the health and condition of the animal itself. Individual micro pigs may have different life spans than each other due to environment, breeding and quality of life.
Health conditions that can affect the longevity of a micro pig are obesity, respiratory illness and arthritis. Once a micro pig reaches the geriatric age of 10, these problems, along with constipation and vision issues, can affect quality of life. Frequent veterinary exams and proper husbandry can help a micro pig live a long, healthy life.
