Backpack to hold small dog - New/unused - $100

Hi, I purchased this backpack for walking/hiking, it's intended to hold a small dog. The quality looks great, but it will be a bit small even for my Havanese so I'd like to try to sell it instead of shipping it back. https://tarigs.com/produkt/hiking-backpack-for-dogs/ Please contact me if you are interested in purchasing it for $100. I have the size Small in Light Grey. Thanks, Laura Grafton St.
