If your back seat is strangely shaped, or you want to use the barrier in multiple vehicles, the Rabbitgoo Dog Car Barrier features an adjustable design that will fit in almost any vehicle. The sturdy metal barrier can be mounted to the seat headrests, with two adjustable panels to extend its height or width as needed. Reviewers say it’s durable and effective, even with large-breed dogs.

Large dogs can often go over, around or through mesh barriers, but the High Road Dog Car Barrier effectively keeps big dogs in the back seat. This barrier features a durable steal frame with chew-resistant mesh. It securely attaches to the back of your front seats.

“My 70 lb. Doberman thinks he’s a puppy and used to try to climb onto my lap — super dangerous when driving, obviously,” says one reviewer. “This item keeps him safely in the back where he can’t distract me from the road and keeps him safe so he can’t fly forward if I have to stop short!”
