A pet car protector and barrier is a device that fits to a car to restrain a pet in a particular area. They should be used with an appropriate car seatbelt for your pet. They can be used instead of a crate in vehicles where a crate would not fit or would not be appropriate. Barriers can be fitted to keep a dog in the cargo area of your vehicle – these are popular in SUVs and wagons. However, they can also be used to keep dogs in the back seat and stop them from trying to get close to the driver. They can be made from hard metal (steel) mesh or from fabric.
