Using your Weaver Leather Aztec embroidery dog collar is easy. 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 cleaning, use a damp cloth to wipe off dirt and debris. Avoid using harsh chemicals as they can damage the leather. Store the collar in a dry place away from direct sunlight to prevent the leather from drying out and cracking. Regularly check the hardware for any signs of wear and tear to ensure your dog's safety.
