爱情道路上的一条狗
[ài qíng dào lù shàng de yī tiáo gŏu]
In literal translation, 'A dog on the path of love' seems unconventional as a metaphor, however, it could depict faithfulness, dedication as dogs typically symbolize loyalty and following someone around wherever they go. On another level, this might imply subservience in love, willing to suffer and beg even if treated badly in romantic pursuits.
