how has boxer changed since the rebellion

Boxer only changes physically throughout the course of the novel, eventually becoming so weak that he's sent to the glue factory. As a character, he never changes from beginning to end. he believes in the cause of the animals and he blindly trusts those who've taken control. He does what he's told for the good of everyone and works hards than anyone. His mottos; “I will work harder” and “Napoleon is always right.”
