Using this dog collar is a breeze. Simply open the quick - release buckle, put the collar around your dog's neck, and close the buckle. 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, you can use a mild soap and water to gently wash the nylon part. Rinse it thoroughly and let it air dry. Avoid using harsh chemicals as they may damage the reflective stripe or the aluminum dee. Check the collar regularly for any signs of wear and tear, especially the buckle and the dee. If you notice any issues, it's time to replace the collar to keep your furry friend safe.
