Size: Approximately 23cm in height (basket only), 35cm in width, and 31cm in depth. This was purchased for use with a French Bulldog, but it seems the dog was too rambunctious and wouldn't go in, so it wasn't used. Therefore, it's only been tried out and is in good condition. French Bulldogs can be quite boisterous (^_^;), so how about it for a regular dog? It's waterproof and can be folded as shown in the photo. It will be shipped folded, so please insert the rods after removing the Velcro, as shown in the second-to-last photo. There are four pockets, and both sides can hold bottles, etc. Attach it to the headrest of a car seat. Please be sure to read the self-introduction before purchasing. * Regarding used items, please understand that they are used.
