Using this collar is easy. First, adjust the collar to fit your dog's neck using the black plastic slide. The contoured quick - release buckle allows you to fasten and unfasten it quickly. Attach your dog's leash to the nickel - plated dee. When it comes to maintenance, you can gently hand - wash the collar with mild soap and water. Let it air dry. Avoid exposing it to harsh chemicals or extreme heat. Always check the collar regularly for any signs of wear and tear, especially at the box - stitched stress points. If you notice any damage, replace the collar to ensure your dog's safety.
