I was at a friend's house one time and sitting on the edge of a bed with his dog seated in front of me .
I was petting the dog and we were both having a fine time. Until I gave it a little breath to the face and that dog jumped up to bite me in the face.
Luckily, I had my hands near his neck and immediately pushed back, but that dog's teeth hit my forehead and my lower lip with its top and bottom teeth, respectively. Blood resulted but it could have been way worse.
