Thank you for viewing. This is a very easy-to-use carrier bag. I've only used it about three times to take my small dog (Chihuahua) to the vet, so it's in good condition with no noticeable stains. By the way, it's a bit large for a Chihuahua (3 kg), but I chose the M size because it's easy to hold a sick dog and put them in from above. - Color: Brown - Material: Mesh, Nylon - Size: M size - Features: Breathable mesh window - Straps: Adjustable shoulder strap - Closure: Double zipper
