Pigs are incredibly intelligent and social animals that are capable of forming strong bonds with their human caretakers. Pigs show affection to humans in a variety of ways, including snuggling, licking, and grunting softly. They also enjoy being scratched and rubbed, especially behind their ears. Pigs are very food-motivated, so they may also try to beg for treats as a way of showing their affection. Ultimately, pigs show affection to humans in whatever way they feel comfortable, and it is always a joy to witness the special bond that forms between them.
