Brown nylon carrier bag for medium-sized dogs, with a mesh door for good ventilation. - Color: Brown - Material: Nylon - Opening: Mesh door - Size: For medium-sized dogs - Features: Foldable I used this when my puppy was small, but they quickly grew and I stopped using it. It depends on the breed, but I think it can fit dogs up to about 8 kg. However, for Shiba Inus, it became cramped at 8 kg, so I switched to a larger carrier. Thank you for looking.
