Well, it could be a really cute story. Maybe your dog was showing affection. It might have been excited to see you and licking your hand was its way of greeting you.
The main ethical concern is the potential for causing discomfort and harm. The 'dog vore' part is extremely disturbing and can be traumatic for some readers. It also blurs the lines between appropriate and inappropriate interactions between animals and humans. Licking in this context, if related to the vore concept, further complicates the ethical issues as it may imply non - consensual or inappropriate behavior.
In a 'big dog licks girl' fanfic, perhaps the girl is new to the area and feels a bit lonely. The big dog, which belongs to a neighbor, senses her loneliness. The dog's licking is a way to break the ice. Then, as time passes, the girl and the dog develop a special bond and she starts helping the neighbor take care of the dog more often.
Yes, there could be. For example, a story where a dog licks a person who has passed out drunk to get help. Maybe the dog senses something is wrong and tries to wake the person up by licking them, and then the neighbors see the dog's behavior and come to the rescue.
One common theme could be friendship. The dog's licking might be seen as a way of showing its friendly nature towards the female reader. Another theme could be rescue. Maybe the dog licks the female reader after rescuing her from a dangerous situation.
No. 'Dog vore' involves disturbing and often inappropriate themes. Fanfic should generally be based on positive, non - harmful concepts. Vore, which implies one creature devouring another in a rather extreme and often gory way, is not suitable for most audiences, especially when combined with the idea of a dog interacting with a girl in such a way.
You can make it interesting by adding some mystery. For instance, the big dog may have a strange mark on its fur and every time it licks the girl, she has a strange vision. This will keep the readers guessing.
