Gentle Dog Steps for Puppies and Senior Dogs Ranked #1 in the Rakuten dog care goods ranking. This dog step uses a single layer of high-density urethane used in bedding, instead of conventional chip urethane (urethane scraps bonded with adhesive). The removable cover uses 100% cotton Oxford fabric instead of PVC (polyvinyl chloride), which can become slippery when wet. In addition, the inner cover is water-repellent, making it safe and easy to clean. *Shipping costs are over 1000 yen, so we cannot offer any further discounts.
