真心错付给了狗
[zhēn xīn cuò fù jĭ le gŏu]
'真心错付给了狗' means 'My genuine feelings were wasted on a dog.' This expresses regret and disappointment where someone feels they gave their trust or heart to an unappreciative person (referred here metaphorically as a dog). It implies wasted effort and a sense of betrayal.
