Merry Christmas Adriano and to all here!
I had a very lucky discovery today. Looking on youtube I found this footage.

Here's the extended footage (unfortunately a lot lower quality)

I am convinced it was filmed on or around the same day that the portrait photos that I bought were taken.
I believe Leutnant Moller is the one who picks up the dog with his glove and passes it around. I recognise 2 other "dog handlers" from the other photos that were on ebay but I didn't manage to win those.
More well known faces in the film include Wolf-Dietrich Wilcke and Günther von Maltzahn.
My Christmas came early!
