Meaning of 'to dog mouth'

[Offroad]

Dear teachers,

It's been a long time. Hope this new thread finds you all well.

Anyway, I'd like to ask if I am correct in assuming that 'to dog mouth somebody' means the same as 'to mouth off...'.


Many thanks.

I'm not familiar with the phrase but I would probably assume it meant the same as "to bad-mouth someone".
