狗 (gǒu) means “dog”, but 狗带 (gǒu dài) has absolutely nothing to do with dogs.
It has entered popular usage these days among youngsters because it sounds like “go die”. You can use the phrase if you want to tell a friend to “go to hell” in a half-joking manner. Definitely not recommended for use when speaking with a stranger.
