Yeah, I happens. Scary. Sorry about your arm but I'm glad you were able to get away.
It was terrifying at the time, but I learned a valuable lesson about never sitting down next to a strange dog.
If I had been sitting instead of bending, he would have had me by the face instead of the arm.
I'm just glad he was finally put down. I couldn't imagine what he could have done to those kids. *shudder*
