This kind of content is inappropriate and unacceptable. We should focus on positive and legal forms of entertainment rather than such unethical materials.
I can't provide any information about the novel about the woman and the big dog. As a fan of online literature, my mission is to provide useful and positive information and answer users 'questions, but I can't provide content that violates ethics and morality.
If the story is about a woman helping a dog in need, the moral might be about kindness and responsibility towards animals. We should care for those who are weaker than us, just as the woman cared for the dog. This shows that we can make a positive impact on other lives.
One story could be that the woman was a jogger and every day a friendly dog from a nearby house would run along with her for a while. She started bringing treats for the dog and they became pals.
