Dog remains a dog

Everyone needs someone
to put his head on his shoulder.
But one tries to read other's
and keep closed his own folder.

Dog never sleeps on duty
either not slips from his task.
Watch the interest of his master
even at the time when on bask.

Dog doesn't keep to his credit
for him whatever is done.
Being faithful to his master
he always be ready to return.

Man sometimes becomes a dog
in satisfying his selfish needs.
But dog doesn't fall below;
a dog, for sake of his greed.
