一看到 bite ，大家是不是就想到了狗，有一种说法：同多数动物一样，狗叫是有两种表现，一种是兴奋，一种是害怕。兴奋是当它看到自己的主人，特别高兴，或是玩疯的时候。而害怕的时候它以叫声想吓退别人，也就是在警告。这样它一般是不敢咬的，所以吠犬不咬人，这个跟今天要分析的习语 all bark and no bite 很类似，可以意为“光说不练，只会动嘴皮子，不打架，吓人的话”等，寓意：
threatening, aggressive, but not willing to engage in a fight
威胁，好斗，但不愿意打架
full of talk, but low on action
满口空谈，但缺乏行动
talk that is more impressive than one can actually do
比实际行动更令人印象深刻的谈话
例如：
I heard he has threatened you with dire consequences if you don not stop that construction. Don't worry, he is all bark and no bite.
我听说他威胁你，如果你不停止这项工程，后果会很严重。别担心，他只是吓吓你。
He looks rough and dangerous, somewhat like a gangster and talks tough, but he is all bark and no bite.
他看上去粗野而危险，有点像个黑帮，说话很强硬，但他不会打架的。
