Using this Carnival dog leash is very simple. Just attach the bolt snap to your dog's collar, and you're ready to go for a walk. When choosing a color, pick one that you like best or that suits your dog well. As for maintenance, if it gets dirty, you can easily clean it with a damp cloth or rinse it under water. It dries quickly due to its waterproof nature. When not in use, store it in a dry place to keep it in good condition. Be careful not to pull the leash too hard to avoid damaging the bolt snap or the leash itself. Also, make sure the attachment to the collar is secure before each walk to prevent your dog from getting loose.
