This is a sling bag that can be used for various pets such as dogs and cats. I received it as a gift, but it was too small for my dog, so I removed the tag, but I still have it. I think it would be convenient for dogs before their first walk, when going out together, or when going to the vet. It seems to have good breathability with its mesh material. I will send it via Mercari delivery U^ェ^U
