I am inclined to think that, while you would likely never admit it to yourself or anyone else, if you take the dog, at some point (or several points) along the way, you'll be more than ready to feed the bears. It's a long ride, and the locals all have big dogs. For instance, my first night in Alaska (at the 1260 Inn) a Husky and a Hybrid Wolf sorted-out issues through my bar stool while I tried to eat my clam chowder. The bartender said they do that every so often. Everybody has a big dog out in the sticks. I just think you're asking for a lot of trouble for you and the cute little 'pup if you take it along. YMMV...
