border collie chow mix

Question
do all chow mix have black tongues

Answer
There are three answers: yes, no, maybe.  I'm not an expert in chows at all, but I have read and heard that along with polar bears and giraffes, they have black tongues, completely black tongues. I think that when you start crossing breeds, the amount of 'blackness' in the tongue can vary even within a litter.

So I guess, not knowing much about how much chow is in a mix, that the dog can have anything from some dark pigmentation to a full black tongue.

Sorry it's vague answer.
