I tried putting my dog in it, but the size didn't fit. There are some scratches on the bottom board from when I put him in, but I think it should be fine for use. Up to 15kg. This is a water-resistant carrier bag that can be worn on your back. It's well-made. It has a waist belt and can be carried on top of luggage, making it less tiring. - Brand: Mandarine Brothers - Model Name: Carrier Bag - Color: Blue, Blue Green - Size: Large - Features: Backpack design - Material: Water-resistant material Thank you for looking. I only tried it out at home, and it still has the tags. I'm selling it at a low price, so please consider it. It will be folded and shipped in simple packaging.
