This is a drive box purchased from Peti that allows your dog to see the scenery while sitting. It can be raised to about the height of the window, so your dog can enjoy the view while sitting, and it's also reassuring for them to be at the same height as the owner. It also has a safety hook to prevent your dog from jumping out. The cover is removable and washable. The cushion inside has different materials on the front and back, so it can be used according to the season. It hasn't been used that many times, but it has been stored at home for a long time, so please refrain from purchasing if you are sensitive to this. Please understand that this is a used item.
