I just saw PeterNYC's thread regarding having a big dog in his X3:

My dog "Beef" isn't really a big dog but she was in the car with me when the bad men crashed it.
I keep her in the little thingy on the dashboard that holds the Navigation (if you have it - I didn't).
I usually put an oven mitt in with her as a cushion.
Beef was sitting there happily waiting for her nightly bite of Bear Claw and a sip of hot cocoa and the next thing she knew she was flying 6 inches through the air and into the windshield.
She's at the Vet still with a concusion - they think.
One eye rolled back in her head but they said it will get better.
I need a bigger car and a bigger dog!
