How does Napoleon handle the problem of Boxer?

Which problem........... there were quite a few!

Napoleon tries to rewrite history here, as the windmill has been destroyed, the animals are seeing more and more rationing, and once again, the pigs are using Snowball as a scapegoat........ But Boxer isn't buying it. He remembers the things that have happened and begins to verbalize them. Then, Napoleon instructs the dogs to kill him, but when he realizes that Boxer is stronger changes his mind. Ironically, none of the animals sees the attack by the dogs as an attempt on Boxer's life........ they think they've just gone a little crazy......... go figure!
