I rewatched this today and couldn't help but notice all the metaphors stuck into the storyline. The dog's death at the end was in particular a heart wrenching and effective way to suggest that the traditional family unit as it had been known up to that time was gone forever.
Two guys... in an airport... talking... That's a little fishy.
After 26 months of having this on the top of my queue with the "VERY LONG WAIT" next to it, it got sent to me. WOW! What an experience.
I like what you say about the symbolism. I think it may mean a little bit more though. Remember earlier when John says that Paul is the most important living animal to him? Look closer to his hand. He is holding a cross. I think that the dog's death can also be taken to a spiritual means. I think that the dog represents Jesus Christ and his death shows that his belief in God is also dead. I think that would also explain why John wanted so badly to move to Wisconsin.
Just my $.02
I think I'm going to watch it again before sending it back to Netflix.
Doesn't it give you a headache asking stupid questions?

Good news! Netflix added it to Instant.
I never caught the crucifix before, but I rewatched the scene in question and it would explain the Wisconsin subplot. The badger in the dream sequence does too.
As for Paul's death, I'd argue that John's later reunification with Hank is a reaffirmation of his faith in God.
I can promise you a day of reckoning that you will not live long enough to never forget.
