Query: I NEED a sequel ;)

I'm a huge dog lover and found this story of walking, talking, intelligent dogs very interesting. There is a sad undertone to the whole story and an underlying thread of darkness , cruelty and the grotesque (the cow, the cow!). Very original and imaginative. The only small complaint I have, and it is because of the way the story is being told (in journal entries and by several different points of view) I'm unable to become connected to any one character or know any of them on an intimate level.My only complaint? I do wish it hadn't ended with so many questions left unanswered.
