Not only is it a convincing sentence, it's humorous too.
"The law is always on your side. You're not in danger. You do have the right to hate the dog. It's not the end of the world. It's like a cat that got a kitten and is biting its owner. Your dog is not safe. I am glad you have a dog, but it's not the end of the world. If you want to kill your dog, go ahead. It's not going to be easy, but you can do it. I promise."
