那头猪很脏用英文怎么说

在英语中，形容猪很脏的常用表达有 "the pig is dirty" 或 "the pig is filthy"。

"Dirty" 是形容词，意思是不干净的，污浊的。

"Filthy" 也是形容词，意思是极其肮脏的，比 "dirty" 更为强烈。

例句：

"The pig pen was dirty and smelly. The pigs were covered in mud and filth." (猪圈很脏很臭，猪都沾满了泥巴和污物。)
"The farmer had to clean the pigs before taking them to the market. They were so dirty that he had to hose them down." (农夫在把猪送到市场之前必须把它们洗干净。它们太脏了，他不得不用水龙头冲洗。)
