Using your Coastal double - layer nylon dog collar is a piece of cake. Just put the collar around your dog's neck and insert the buckle tongue through the appropriate hole for a snug fit. The D - ring on the collar is where you can easily attach your dog's ID tags and leash. When it comes to maintenance, if the collar gets dirty, you can hand - wash it 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, like fraying nylon or a loose buckle. If you notice any issues, it's time to get a new collar to keep your dog safe.
