I bought this because it's a good size and cute, but my 10kg Shiba Inu never went inside, and ended up playing on the roof and crushing it. Therefore, I'm selling it at a lower price than when I bought it. Width: 55cm, Length: 43cm You assemble it by opening the zippers and inserting the firm urethane foam (pictured) on both sides and the roof. It's a large item, so shipping costs will be high. I will not be offering any discounts, so please consider this and check the pictures before making a purchase. Please also check my profile.
