Thank you for viewing. I used this for about three months for a Jack Russell Terrier puppy. I washed it and removed hair, but there may be some residue. Please refrain from purchasing if you are concerned. This is a harness made of breathable mesh material for comfortable wear. It's easy to put on and take off, and it's very easy to use, so I recommend it. - Brand: curli - Size: Please refer to photo ⑦ for the size. - Color: Blue - Material: Mesh
