This is a 7-piece set for small breed female dogs. I think the weight is around ~2.5 kg. A slender dog might fit up to 3 kg, but my Chihuahua x Pomeranian mix, who weighs 3.5 kg, found it tight. I think the size is SS... Includes winter and summer clothes. They show signs of use, but are still usable. They have been washed and stored, but are stored by a private individual. Thank you for looking. This will be sent anonymously and with simple recycled packaging. Returns are not accepted after shipping, so please ask any questions before shipping, even after purchase.
