There are a number of reasons why your pig may nudge you. It could be that your pig is trying to get your attention for something specific, such as wanting to be fed or petted. Your pig may also nudge you as a way of showing affection or as a form of social bonding. Pigs are highly social animals and enjoy physical contact with their owners. If you find that your pig is constantly nudging you, it is likely because your pig enjoys your company and wants to be close to you.
