I recently aquired a Female Columbian that I look to pair up with a potential dominant hypo. The Female had a definite case of nose rub and due to this i was able to get it cheaper than normal. the rub itself is but i can't help but think that the snake is having a hard time breathing out of its nose, due to the fact that it is breathing out of its mouth. I am pretty positive it is not a respitory infection, because the pet store i work at is constantly dealing with big snakes. Any help would be appreciated.
