This was purchased by my sister several years ago, but it was too small for her dogs, so it has been stored unused. I am a novice and this is my first time measuring, so there may be errors. Dog Donki Polo Shirt Neck: 25cm, Chest: 40cm, Back Length: 23.5cm, Front Length: 12.5cm Estimated weight: Up to ~3kg The fabric is thin and stretchy. I think it would be suitable for small dogs and puppies. Although it is unused, it has been handled by people, so please refrain from purchasing if you are sensitive to this. Thank you for viewing.
