A halter is headgear that is used to guide an animal; it fits
over the back of the neck and across or around the animal's
muzzle so that, when a handler pulls on the muzzle end of the
halter, the animal's head turns towards the handler.
Halters are commonly used on
horses and
sometimes on cattle,
dogs, and other
animals.
The primary difference between a halter and a
bridle is that
the latter has a
bit
that goes into the animal's mouth, providing even greater control.
