A pig has four toes on each foot, but it only walks on the two larger middle toes. The two outer toes do not typically touch the ground when the pig is standing. These toes end in hooves, and the structure is called a cloven hoof. This means the pig has a total of 16 toes—four on each of its four feet—with two of those toes on each foot bearing most of the animal's weight during walking.
