dog is one of the most popular pets in the world. It ordinarily
remains loyal to a considerate master, and because of
this the dog has been called man's best friend. Class
distinctions between people have no part in a dog's life.
It can be a faithful companion to either rich or poor.
Dogs have been domesticated for most of human history
and have thus endeared themselves to many over the years.
Stories have been told about brave dogs that served admirably
in war or that risked their lives to save persons in danger.
When Pompeii--the Roman community destroyed by Mount Vesuvius
in AD 79--was finally excavated, searchers found evidence
of a dog lying across a child, apparently trying to protect
the youngster. Perhaps few of the millions of dogs in
the world may be so heroic, but they are still a source
of genuine delight to their owners.
