Analysis of Authorship in "Two Dogs and a Ball"

This week, we are trying to discover who the "author" is of each piece. After viewing "Two Dogs and a Ball" I believe the author of the piece is both the man behind the camera as well as the two dogs in front of it. Being an owner of a Weimaraner I am very familiar with William Wegman's works and it seems to me as if the dogs actually have a good idea as to what's going on then one would think. I think what separates the dogs from being actors is the fact that they aren't humans that can communicate allowing them to act freely with no real direction but their own senses.
