Using this dog collar is easy. First, measure your dog's neck accurately and follow the sizing guide to pick the right collar. Put the collar around your dog's neck and fasten it at the appropriate hole for a snug fit. Make sure it's not too tight to avoid discomfort. When it comes to maintenance, keep it away from sharp objects that could damage the leather. Wipe it with a soft, dry cloth regularly to keep it clean. If it gets wet, let it dry naturally away from direct heat. This way, your dog's collar will stay in good condition for a long time.
