Using this Digby Fox dog collar is a breeze. Just put it around your dog's neck and fasten it. Make sure it's not too tight or too loose. You should be able to fit two fingers between the collar and your dog's neck. When it comes to maintenance, use a soft, damp cloth to wipe the collar clean every now and then. Avoid exposing it to extreme heat or chemicals as this can damage the leather. Also, regularly check the brass fittings for any signs of wear or looseness. If you notice anything wrong, it's best to replace the collar to keep your dog safe.
