She would ride in the passenger seat with me going everywhere and just lie there calmly the whole time.
That theory works right up until someone puts a Saab through your engine. Had my dog been in the front seat, he would have gone over the dash, into the windshield and been seriously injured or killed. As it was, he was in a crate in the back, physically unharmed (though two years later, he still refuses to get in the car on his own).
It doesn't matter if your dog lies there calmly or paces circles on the seat, they are the same 25 pound projectile sent through the windshield, or in an older car, smashed into the airbag and killed.
This is not a topic where we say "aww, my doggie might not like it". I wouldn't leave my child in the front seat unrestrained either, even if they don't like it or were uncomfortable.
The only mitigation here is if your dog lays in the footspace on the passenger side. The forward motion is minimal, and they are out of airbag/glass range.

. I know that happened a while back, but I'm glad everyone made it out ok.
