The pigs lie to the other animals by changing the commandments without the other pigs knowing. They do this by adding phrases at the end of the commandment. This makes the other animals think that they just forgot the last part of the sentence so they don't suspect anything. One example is the commandment "No animal shall kill any other animal." (88) The commandment now reads "No animal shall kill any other animal without cause." (88) The pigs do this so that Napoleon could kill a group of animals that he suspects are working with Snowball against the farm. Napoleon made everyone think that Snowball is a subversive against animal farm. Two other examples are "No animal shall drink alcohol" (103) and "No animal shall sleep in a bed." These commandments change to "No animal shall drink alcohol to excess" (103) and No animal shall sleep in a bed with sheets." The pigs do this for their own luxury. Only the pigs are the ones who drink alcohol and sleep in a bed. The pigs lie by changing the commandments to help themselves.
The second way that the pigs lie is by openly deceiving the other animals. When the brawny boxer is injured the pigs say that he is going to a hospital to get better. When the truck came to pick boxer up some of the animals see that the truck is really for picking up horses to be in a glue factory. When the animals confront Napoleon he says that the truck was really going to the hospital but the hospital forgot to change what it say on the truck. Here Napoleon lies two
