This dog was outside the other Christmas market we went to that evening, near St. Stephen's Basilica, from which I'll post a few pictures.
She was just delightful, and although she looked like a guide dog, we couldn't figure out who she was guiding. She certainly enjoyed visiting with strangers! What looks like a snarl was just the way her face was ;-).
I guess I must have looked quite frustrated because I was having a hard time getting a picture since the dog was moving all over the place and it was getting dark, so her human made her sit down and pose.
