Using this dog collar is super easy. Just open the quick - release buckle, put it 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 maintenance, you can wash it with mild soap and water every once in a while to keep it clean. Keep an eye on the anodized aluminum dee and the buckle for any signs of wear. If you notice any damage, it's time to replace the collar to ensure your dog's safety.
