Arthur is still on the move at thirteen. We've been to beaches, state parks, festivals, big cities, and small towns. He's marked his way up one side of the state and down the other. If your dog is hyper in the car, plan on some sort of restraint. A portable dog kennel or gate will keep the dog safe and prevent him from driving.
Dogs love to drive.
They're lousy at it. They are good at distracting you when you are driving. A little training also goes a long way. Whatever you do, don't travel with a dog who hates the car. You'll end up hating the dog, yourself, the car, travel, and the world in general.
