Are there any examples to show that Boxer is loyal to Napoleon?

Consider Boxer's two mantras for being as examples of his
loyalty.  When he says, "I must work harder" and "Napoleon is always right," it is
representative of his loyalty towards Napoleon.  It is also indicative of how committed
Boxer is to the ideas of Animalism, tenets that Napoelon claims to embrace.  Boxer is
not afraid of demonstrating his loyalty towards Napoleon's leadership in his working on
the windmill more than any other animals.  When he gets the rooster to wake him up
before all other animals, Boxer reflects his sense of devotion to Napoleon's rule and
the wishes of his leader.  Boxer is loyal to Napoleon in the most honest of ways.  There
is no duplicity or ulterior motives in why he works as hard as he does.  Rather, he is
committed to the idea that whatever "Comrade Napoleon" decides is for the best.  It is
for this trust in Napoleon that Boxer never ends up learning how to read beyond the
first four letters of the alphabet.  He believes in Napoleon in such an intense manner
that if Napoleon knows how to read and write, it is enough for Boxer.  The old cart-
house never quite understands how Napoleon only needs him for his physical service, such
as defense of the farm or for the building of the windmill.  When Boxer's lung collapses
and is dying, he believes that Napoleon will look out for his own best interests,
telling Clover that he looks forward to learning how to read and spending time with
Benjamin.  Boxer does not realize that Napoleon has made plans to dispose of Boxer,
something that ends up demonstrating how Boxer's trust and loyalty towards Napoleon is
something that ends up destroying him in the end.
