There is a famous saying, once bitten by a dog, what is the next sentence?

The next sentence is "once bitten by a snake, twice shy"!

However, the next sentence of "once bitten by a dog" is: "I am often afraid of dogs barking"!

This is my personal experience. That dog has long and poisonous teeth. Please don't tease the dog and let it bite … it's too poisonous! ! !
