Dog loves it as a bed in the house. It worked ok as a way to keep her in the seat when placed in the front seat (where I could keep pushing her back in), but in the backseat, the dog wormed her way out of it and was sitting beside it, with the leash pulling on her neck. Higher sides might work better. I have a carrier with a cover that keeps her contained for car rides (which she doesn’t like because she can’t see anything), so I thought this would be better, but it’s basically a bed with a leash. If your dog doesn’t want to stay put, they won’t.
