This is a Pet Paradise dog toy hurdle. It's made of a soft, plush-like material, so it's safe even if your dog bumps into it. The bar of the hurdle is removable, allowing you to adjust the height freely. I haven't used it much, but it has been stored at home for a long time, so it may show some signs of use. Please understand that this is a used item and accept it as a pre-owned product.
