Describe the execution in the farmyard

"For instance, in Animal Farm's public execution, Orwell lays bare the matter of execution by having the dogs rip out the supposed traitors' throats."

Here is some greater detail from GradeSaver,

Napoleon’s dogs drag out of the crowd the four pigs that had opposed the cessation of Sunday meetings. The dogs try to drag Boxer out as well, but he deflects them. The pigs confess that they collaborated with Snowball in destroying the windmill and were planning to help Mr. Frederick overtake Animal Farm. They also confess to knowing of Snowball’s partnership with Mr. Jones for years. Then the dogs tear out the four pigs’ throats.
