Since dogs are considered to be loyal and diligent, the word is included in more than 10 Chinese metaphors.
For instance, "serve like a dog or a horse," is used to describe someone who is ready to render his humble services to the authorities.
"Dogs don't bark to their owners" is an idiom usually adopted to represent the loyalty of ministers to their monarchs.
A love of dogs is not particular to Chinese. In English, people use the phrase "tired like a dog" to say they are exhausted and say "love me, love my dog" when they hope their partner loves the way they are.
Coincidentally, there are phrases expressing these meanings in Chinese, proving again that we are not that different.
