I would get a special box for all the dog things, and pack it last at the old house and first at the new house. I would also get extra special treats and toys for the ride if it is going to be a long one.
We moved a few months ago, but it was a different situation because our new house was only half an hour away and we had proffesional movers. Before move in day we took zoey to the new house to let her sniff around it, and we had been working in it to remodel for months before we moved so it already smelled like me, which i think helped. What freaked her out though was the moving men, so what i did was bring her in my truck. we left at the same time as the moving men, then went to the pet store, took a walk, etc, and didnt come back to the new house until the moving men finished.
