Using this Coastal dog collar is a breeze. First, adjust the collar to fit your dog comfortably around its neck. You can easily do this with the adjustable design. For walks, simply attach your dog's leash to the buckle. If you're using it for a tie - out, connect it securely to a suitable post or anchor. When it comes to maintenance, you can wash the collar with mild soap and water to keep it clean. Avoid using harsh chemicals as they might damage the material or fade the colors. Always check the buckle and the overall condition of the collar regularly to ensure it's safe for your dog. Remember, the product you receive might have 'Coastal' written on the metal buckle or it might be blank.
