We have FidoRido Car Seat Belt for our Shih Tzu and Chiweenie which work great for allowing the dogs to see out. We got Kurgo vests to use because we thought they were more secure than the vests that came with the FidoRido. We use the straps to secure the seats to the car. They make is much easier to remove the seats when necessary. I think these will definitely keep the seats from flying about in a crash.
