A muzzle is a device that is placed over the
snout of an animal to
keep it from
biting or otherwise opening its mouth.
Muzzles are sometimes used on untrained
dogs, large or small, to prevent
either unwanted biting or unwanted barking. They can also be used on aggressive
dogs or other animals. They
are usually made with a strong
buckle or other fastening device to ensure that they do not come off
accidentally.
Muzzles can be primarily solid, with air holes to allow the animal to
breathe, or formed from a set of straps that provides better air circulation and
allow the animal to drink. Leather, wire, plastic, and nylon are common
materials for muzzles. The shape and construction of the muzzle might differ
depending on whether the intent is to prevent an animal from biting or from
eating, for example.
Dog muzzles can be found in most
pet supply stores.
