Before we moved back to town, we had a rat terrier and I've never seen a dog that liked to ride as much as he did. You'd have a hard time beating him into the car or truck unless you locked him in the house before you went out. And unless you went more than 20-25 miles, he was constantly on the move, trying to see out all 4 directions.
And now we have a Chihuahua and she likes to go, too, but if it's just me and her, she promptly lies down in the floor on the passenger side and sticks her head under the passenger seat and she'll stay right there until we stop, then she'll jump up in the seat to look around. But if my wife goes along, then the Chihuahua wants to sit in her lap.
