Using your Lazer Brite reflective dog collar is easy. Just adjust it to fit comfortably around your dog's neck. Make sure it's not too tight or too loose. When walking your dog at night, the collar's reflective material will help keep them visible to cars and other people. As for maintenance, you can gently hand wash the collar with mild soap and water. Let it air dry completely before putting it back on your dog. Always check the collar regularly for any signs of wear and tear, and replace it if needed. If you're using the matching leash, follow the same care instructions.
