At UBahn Wilmersdorf there are two Christmas stalls .The first grills sausage and steaks .This is where I met Bailey who sat glued to her owner in the expectation of a meaty treat . Never once did these eyes leave those of her owner. Asking about a photo the answer was ja . Re the chances of a piece for a reward , nein. Seems Bailey has a strict diet and her owner sticks to it. There was no whining or barking simply perfect behaviour.
