Using this dog bandana is super easy. Just drape it around your dog's neck and adjust it to a comfortable position. It's designed to fit most dogs, so it should sit nicely without being too tight or loose. When it comes to maintenance, since it's made of 100% cotton twill, you can toss it in the washing machine on a gentle cycle. Use mild detergent and let it air - dry. As for precautions, make sure to check the bandana regularly for any signs of wear and tear, and if your dog seems uncomfortable wearing it, take it off immediately.
