It's XL size. See photo 8 for the size chart. I bought it for my Shiba Inu, who was around 7 kilograms at the time. I tried it on, but it seemed uncomfortable. Also, the dog's weight seemed to put pressure on its groin. I haven't used it since then, and it's been sitting in the dresser. It hasn't been washed. There might be some dog hair on it. It might not fit even if the size is correct. I plan to ship it via Yu-Packet Post, which might require a bit of squeezing. #Dog carrier #Pet carrier
