puppy love千万别理解成“小狗的爱”，真实含义是早恋；初恋；青少年的初恋；少年不成熟的恋爱。

【例句】
At my nineteenth year, the puppy love like a falling star bumped my forehead.
十九岁那年，初恋像一颗流星撞到了我的前额。

As she was preparing supper, the doorbell rang. There stood her puppy love. She could not turn him away, as they were friends now.
在她正准备吃晚饭的时候，门铃响了。站在那里的是她的初恋。她不能赶他走，她们现在是朋友。
