Yes, pigs are generally considered peaceful animals.
Pigs possess a complex social structure and exhibit peaceful behaviors within their communities. Part of this peaceful interaction stems from their established social hierarchy, which piglets begin forming shortly after birth. This stable hierarchy contributes to reduced conflict and promotes harmonious living. While they can be assertive in establishing dominance, especially around resources like food, their overall demeanor is far from aggressive when living in appropriate environments. It is crucial to note that their behavior is also heavily dependent on their environment and how they are treated. Stressful or overcrowded conditions can lead to aggression.
