Pigs and hogs are both members of the same family of animals, known as SWINE. SWINE is a term used to refer to any animal in the Suidae family, which includes pigs, hogs, and boars. Pigs and hogs are similar in many ways, but there are some key differences between them. Pigs are smaller than hogs and have shorter legs and snouts. Hogs are typically larger and have longer legs and snouts. Pigs are also more docile and easier to domesticate than hogs.
