Why Do Pigs Squeal?
Pigs squeal for many of the same reasons babies cry. Squealing is the basic way a pig communicates feelings of fear and uncertainty. Whether caring for farm pigs or pet pigs, understanding common concerns of pigs is helpful in knowing how to respond to their squeals.
Fear is the primary driver of many pig squeals. When pigs move to a new environment, squealing is common, but they adjust fairly quickly. When piglets are carried, squealing is common due to fear of falling. The best way to prevent this fear is to wrap the baby pig in a blanket. Squealing may also indicate pain when pigs fight with each other or are attacked by predators.
