Circus Dogs?

These two dogs were shut up in a large pen outside the circus tent in Monaco. I was photographing the lions, elephants and sea lions when I saw this beautiful face peering through the bars.

The big one is a Newfoundland, the smaller one is a mix. Both gorgeous dogs but not very happy. I don't know if they were part of a circus act or simply dogs belonging to a member of the circus and kept in this pen for the day. You can see other shots on Monte Carlo Daily Photo.
