Rule 63, Anthro Pet Scooby

Nice, keeping the whole gang together instead of removing the girls. Not only that, but you're wanting the talking, sapient, titular dog to be more human, while also keeping him as the gang's pet. Sounds spicy~

For the sake of time and chapter usage, let's call the girls you used to know Daniel "Danny" Blake & Valentine "Val" Dinkely, and get a Scoob that carries a gut well.
