Accordion with dog

It's time for another dog photo. This is again from Lisbon and I hope it is another one which raises more questions than it answers.  I also like the shades of gray of the accordion and how the patterns of the cobbled pavement fit in with the composition.

I have two versions of this photo which are virtually identical except for where the dog looks to. I'm never totally sure which one is better, but I've chosen this variant today.
