Using this dog collar is easy. Just fasten it around your dog's neck, making sure it's not too tight or too loose. When choosing the size, measure your dog's neck carefully to ensure a proper fit. As for maintenance, keep it away from excessive moisture and dirt. If it gets dirty, you can gently wipe it with a damp cloth and let it dry naturally. Avoid using harsh chemicals as they may damage the tweed or the leather lining. When not in use, store it in a dry and cool place to keep it in good condition.
