Squealer is short, fat, twinkle-eyed and nimble, "a brilliant talker." He has a way of skipping from side to side and whisking his tail that is somehow very persuasive. They say he can turn black into white! That's just what he does, again and again: every time the pigs take more wealth and power, Squealer persuades the animals that this is absolutely necessary for the well being of all. When things are scarce, he proves that production has increased- with figures. He is also the one who makes all the changes in the Seven Commandments. In human terms he is the propaganda apparatus that spreads the "big lie" and makes people believe in it.
Squealer is a very important character in this novel. Squealer is the only animal in the farm that can make black look white. During the worst days of animal farm, squealer would come happily whisking his tail ready to do what he was best at, talking. Squealer would do anything for his job, he would even lie sometimes but what he really used was words. Squealer convinced the animals that Napoleon was a great leader that all of the animals should defend and be proud of him, but what truly was happing was that Napoleon wasnt actually doing anything unless breaking the animal farm rules. Squealer is the one in charge to tell the rest of the animals that Napoleon is great and victorious, while he is probably breaking the rules or even changing them. The proper morph for Squealer is a Propaganda man for a great leader.
All around the story whenever you see Squealer, he will be talking to the rest of the animals. Squealer was always very convinced that all animals believed him at all time, but he also knew when they didnt believe or when they knew he was lying. We can see this at the last chapter when Squealer looks suspiciously at the animals in the barn meeting. For anything Napoleon wanted that was not in the rules he would get it but very smartly he would be backed upped by Squealer. By this way Napoleon had a perfect life. Squealer was specially used to make Napoleon look good when he used western influential gatherings.
Squealer is very happy on his position. What he thinks is important is that Napoleon has absolute power so that he can still eat apples, milk and other privileges. Doing this Squealer and Napoleon depend on each other which is why they are not separated or corrupt each other, like Snowball and Napoleon did. Squealer also very smartly does not want to assume absolute power, which I personally think he could, because he fears the dogs and he also knows that if something goes wrong he does not want to be responsible for any failure. This way he still has his privileges and not assume a lot of responsibilities. As we can also see that Squealer does not abuse on his limited power, this may be because he can predict an unpleasant consequence of Napoleons dogs.
Most importantly is what the others think on Squealer, besides this is very important for his reputation. The animals all think that Squealer is one of them. They think he wants to protect them and that he is ever so loyal to him. They also think that Squealer likes them and works for them and they dont think he is bad and that he breaks the rules. Napoleon uses Squealer more like a weapon of communication and propaganda. But Squealer knows that Napoleon is using him, and he makes the best of it. He doesnt care that Napoleon is manipulating him because he knows that while Napoleon is still in power he will still get the Milk, apples and the other beneficial goods.
In my opinion Squealer is one of the most intelligent characters in the novel. I like the way he makes people depend on him and on the way he predicts what will happen if he does something. Squealer is also my favorite character because he makes on what he has the best of it. He also persuades the whole farm on his personality.
