This is one of the funniest things I've read in a while. U need to read the whole thing. The dog reminds me a lot of our long-gone Coonhound-Doberman mix, Diablo. I can totally seem him doing something similar. He used to go out on day long walk-abouts through the woods, across the river, maybe chase some farm animals around and then be home just in time for dinner.
