Using this collar is a breeze. Just put it around your dog's neck and use the quick - release buckle to 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. Since it's not recommended for tie - outs, don't use it to secure your dog outside for long periods. To keep the collar in good condition, clean it regularly with a mild soap and water. Avoid using harsh chemicals as they can damage the nylon and plastic parts. After cleaning, let it dry completely before putting it back on your dog.
