Horse's- some body, please help me understand..

Here is just a quick image of a horse that i have seen locally in a field near to where i live.
Its covered in flies and smells, so please someone help me understand the love and admiration people have for these animals?
Is it a status thing? "ooo we own a horse"?
or do they really give you joy and love back?

They cost an arm and leg in bills, and unless you have a nice plot of land,
will live miles away from your home.

To be honest my dislike is the blank look they have...
A dog say, if it is going to kill you its obvious,
from the tell tale signs. foaming at the mouth, the narly teeth and just general vibe.
Where as a horse...
It might kill you, or want to mate with you,
and you will never know...
