Bia chews on wood and PAPER all the time!! I always wonder if she swallows it because I know it must hurt going down. I try and move everything out of reach for her that she can chew, but a lot of my sons toys are made from wood, and so she will still a block or something and hide it from me, then chew on it under my bed. I just found out her little hiding spot today when she was no where to be found. I also found all the stolen chewed up toys too! I really wonder what it is, I have never seen any other dogs chew wood or even paper. IS it
harmful?
