This bandana is handmade for you to order and top stitched to a high finish. 100% cotton the bandana can be washed at 30 degrees and gently ironed. We have tested this extensively as we both have gorgeous but mucky Labradors. Sizes are a rough guide to help you choose the best fit for your dog. This is a fun pet accessory so please make sure that it is suitable for your pet and check for wear and tear.
