The newborn pig has eight needle teeth, sometimes referred
to as wolf teeth which should be clipped within 24 hours after
birth. They are located on the sides of the upper and lower jaws.
Clipping these teeth is necessary because pigs may bite each
other and the sow's udder, leaving small cuts to become infected.
The irritation may be so severe that the sow might refuse to
nurse the pigs.
