Looking for the name of short film that I saw back in 1975 or 1976. It
was on HBO. This was when they used to play short films in between the
feature presentations. The film was of a man walking his dog in the
park and was shot entirely from the dogs point of view. The only other
details I remember were that the dogs owner was played by Paul
Benedict and that there wasn't any dialog in the film. It just had an
instrumental piece of music playing as its soundtrack.

I've tried checking Paul Bendict's acting credits but it doesn't seem
to list this one. I know it's a long shot but this is one of those
questions that has haunted me for years.
