你配狗才长久
[nĭ pèi gŏu cái zhăng jiŭ]
This nickname uses wordplay and carries an implication of longevity and loyalty as 'you' (you, 你) sounds like 'forever' (永恒 yǒnghéng) when combined with dog's longevity in Chinese belief. This can be seen as a funny way to emphasize companionship that lasts over time, similar to a loyal relationship between people and dogs.
