Using this dog collar is easy. Just put it around your dog's neck and fasten the buckle. Make sure it's not too tight or too loose. For a good fit, you should be able to fit two fingers between the collar and your dog's neck. When it comes to cleaning, you can use a mild soap and water to wipe it down. Avoid using harsh chemicals as they might damage the collar. Check the collar regularly for any signs of wear and tear, especially at the stress points and the buckle. If you notice any damage, replace the collar to keep your dog safe.
