Plastic carrier bag for medium-sized dogs, top-opening with ventilation holes. - Color: Black - Material: Plastic - Opening Type: Top-opening - Size: For small to medium-sized dogs - Ventilation: Side ventilation holes Thank you for looking. I am selling this because the size is no longer suitable for my dog. I mainly used this when traveling in the car, so there is some wear and tear, but it is still in good working condition.
