Unfinished [Smile.dog x Canine! Reader]

[Name] was a [breed] dog, one whom was mistreated by her owner. One night, her mistress comes home extremely late and just as drunk. However, she doesn't have a chance to hit [Name]. This is all thanks to a man in a white hoodie and his beastly looking husky. Now homeless and free, [Name] seeks to repay this human named Jeff and his pet called Smile- but is she suited to be the canine companion of a serial murderer? Before long, the [size] [breed] realises that she has some unfinished business- in the form of her undead mistress.
