There he could enjoy the breeze and watch the people go by, but would not get away. A good solution for a large and gentle dog. Apartments are small for the most part in the village, and it can be hard on large dogs. And backyards are few, so here he was. And he became a mascot in my mind.
So on my last visit in June, I was sitting in Le Pain Quotidien on Hudson and I saw him! I leapt out of my seat and ran out to get a picture for my own sake. He's got to be seen to be appreciated.
And a second snap of him in all his largeness (pls. Click on the pic to enlarge). He's just about the size of those bicycles behind him, but this angle doesn't do his stature justice.
It was cool this day, but I remember seeing him on sweltering days and thought, "How does he handle the heat with all that hair?"
I have no idea as to his breed and have been looking on the internet to no avail. It's probably just easier to ask you -- do you know what he is?
