This dog carrier backpack offers safety, comfort, and durability for your beloved dog!! Used only once, but I wasn't used to it, so it's in excellent condition with no stains. I will remove as much hair as possible, but please understand that it is not unused. To prevent the zipper from coming down during use, you can use the hook attached to the zipper and attach it to the buckle around the neck of the backpack for safe use. Includes a removable storage mini bag (35x22cm) ■ Size: M size ■ Color: Black - Model: K9 Sport Sack Plus 2 - Color: Jet Black - Design: Backpack-style carrier bag Thank you for looking.
