Fifteen Dogs (1970)

A debate between Hermes and Apollo on whether animals would be happier if they had the same cognitive and speech abilities as humans leads to a group of ordinary dogs being gifted these powers as a test. Suddenly aware of time, love, power, and their own mortality, the canines struggle to navigate a world that is no longer purely instinctual, and their once-unified pack fractures into competing visions of how to live, through domination, art, faith, manipulation, and love.
