Dogs don't have many things they fancy more than cheese, ice cream and riding in the vehicle. Every dog that we ever owned is always in a rush to get in the car. People can get jaded, and occasionally they want to feel that fresh air again, dogs can be that way too.
Many years ago, pet safety in the car wasn't really something we thought about. We let our dogs roam in the back portion of the station wagon, sometimes even sitting in the front seat, (actually, our dogs preferred the front seat - better view that way and feeling more like the Big Dog!), and unrestrained. We didn't have the products that are available now to provide a safe traveling environment for our pets. Before, roaming about under our feet, jumping in our laps from glass to glass, and licking us constantly as a way of thanking us for bringing them along were freely done by our dogs as I try to keep on the right lane!
