A few tips from the road...

Always have a dog bag handy - it makes it so much easier when you stop. A bottle of water, food, treats, leash, toys, poop bags and a long leash for when you want to give him a little more freedom to move around while you are doing other things. Also, remember when you are crossing the border that you need to have a record of shots which your vet can provide - it only takes a few minutes but will save major hassles at the border...I suggest leaving a copy in the glove box so you never forget it. It also makes sense to scope out vets in the area you are going and also groomers - had an incident where Echo got into a massive bush or burrs and had to take him for a shave..
