Ditto on the long lead! It can definitely be a lifesaver at rest stops, to just let them stretch their legs. Having a blanket that smelled like home/his bed helped too. I just took one of the sheets he lays on at the house, put it in the car. When we got to the hotel, I spread it out on the bed. It helped greatly compared to the first time around when we had nothing. They sell travel bowls in places like Petco and such. I have one that folds up, it's good for when we stop. But we usually use a water bottle more often. (As it turns out, moving car + moving dog + water bowl = a huge mess in my case.) I just flip it over my head while driving, it isn't too distracting or anything. He gets his drink, and I screw the top back on. I have one like this, but I know they sell just the caps you can put on any water bottle, too.
