Who's Driving?

I have dogs and like most dogs they love car rides. When I start my "taking the dogs in the car" routine in the house, they know and they get excited. But not all places we take them are great. One of them doesn't particularly like the Vet.

I ofter wonder about the trip for their perspective ...

1. Do they care where they're going?
2. Who do they think makes the decision on where to go; Me or the Car?
3. Do doors open because I'm there or do I make the doors open.
