Dog clothes, size M, thin fabric I only used it when taking my dog for walks. I'm selling it because my dog has outgrown it. There are some pills on the collar? See photo 3. The fabric doesn't stretch much, so it might be difficult to put on a dog that is a perfect fit. Washed at home. Back length: approx. 25cm Chest: approx. 35cm Neck: approx. 26cm Size: M, Color: Pink
