Using this dog collar is easy. Just put it around your dog's neck and fasten the buckle. When using, make sure the collar isn't too tight to avoid discomfort for your dog. As for maintenance, keep it away from sharp objects to prevent scratches on the leather and hardware. You can clean the leather with a soft, damp cloth every once in a while to keep it looking nice. If you store it for a long time, put it in a dry place to avoid moisture damage.
