Modern tale of a lonely gay man and his dog. Funny beginning. Sad, but hopeful ending. I don't really understand the middle part other than the "octopus" causing him to have a psychological break with reality. 
 Moral of the story for me... 
 1) I love animals and I think dogs are a such a special gift, but it's the truly the human connection that is needed to find balance, joy, and meaning in our lives. 
 2) (view spoiler)[ Grief for the loss of an animal we love just SUCKS! I've been there. (hide spoiler)]
