In the book Animal Farm, what are some specific examples of how the character Boxer shows blind loyalty?

No other beast in George Orwell's Animal
Farm shows more blind loyalty than the hard-working Boxer. He is the perfect
example of the simple worker who believes everything he is told and toils to the best of
his ability. Boxer is so taken in by the rebellion that he doesn't bother to educate
himself; instead, he works harder than any of the other animals at all times. He
deliberately works longer hours to serve as an example to the other animals, and he
doesn't complain when the rations are reduced. He works when he is injured, and when it
comes time for his promised retirement, he blindly expects to enjoy a life of leisure
during his later years. When the horse slaughterer comes to take him away, Boxer enters
the wagon willingly, believing that he will be treated for his illness. Boxer never
questions the pigs' orders, believing that "If Comrade Napoleon says it, it must be
right." His favorite slogan--"I will work harder"--shows his belief that hard work will
be repaid by the loyalty of his leaders.
