Miniature pigs kept as pets face significant welfare challenges from misrepresentation of adult size, inadequate space, improper diet, and owners unprepared for highly intelligent animals with complex behavioral needs.
Companion pig welfare failures stem primarily from acquisition decisions based on false expectations of size and temperament. Animals purchased as palm-sized babies become 100+ pound adults whose rooting, foraging, and social needs cannot be met in typical home environments. The intelligence that makes pigs appealing as companions - problem-solving, personality, emotional complexity - also means that boredom and frustration cause significant psychological distress. Pigs relinquished to sanctuaries show behavior consistent with previous deprivation including food hoarding, aggression, and stereotypies. Welfare-centered companion pig keeping requires a farm or large property, outdoor access, compatible pig companions, and realistic understanding of the 15-20 year commitment.
