I did too.... but she's not to bright.
Literally, her body was outside the jeep head was in.
Ah yeah, (it's been a while since I've had the top down...) we use a harness too... it fastens at her chest so that keeps her more in the jeep, she can't get her body out no mater what direction she tries to go... although I did open the tail gate at the dog park and out she jumped
there she was hanging upside down a few inches off the ground, she didn't appreciate that much
I do like that net that was linked, the inside one and the outside, I may look into that.
