Looking for a Car Seat for pets

I always travel with my 2-year-old chihuahua, I'm thinking of buying a special car seat for her because she is running wild inside the car, upon checking I came across with this [URL="http://www.petstreetmall.com/Dog-Car-Seat/616.html"]dog car seat[/URL] when I was checking some store. I think with this dog car seat it helps protect my dog from a car accident and will also help eliminate distractions for me while driving They have a variety of brands to choose from. Has anyone tried s brand of seat cover for dogs? Would you recommend it? How is it?
