Using this dog winter clothing is easy. Just put it on your dog like you'd put on a regular piece of clothing. Make sure to choose the right size from the size chart to ensure a comfortable fit. When it comes to maintenance, it's best to machine - wash it in cold water with a gentle detergent. Avoid using bleach as it might damage the fabric. After washing, let it air dry. And always check the clothing for any signs of wear and tear before putting it on your dog again.
