I used this bag about three times as a mother's bag, not for a dog. There are stains inside, as shown in the photo. * One of the straps for attaching to a stroller is missing, but I recommend using the shoulder strap as the Velcro type is not very strong and won't hold much weight. Bottom width: 37cm Height: 22cm Depth: 13cm Shoulder strap width: 4cm Shoulder strap length: 70-130cm Water-repellent and stain-resistant
