Who are the main characters in the 'the black dog story'?

I'm not sure as the details are not given, but it could be a person who encounters the black dog.

In the 'the black dog trucking story', it's likely that the lead characters would be the truckers themselves. They are the ones who are the heart of the story. They would have different personalities, some might be experienced veterans, while others could be new to the trucking world. There may also be dispatchers or managers in the company who interact with the truckers and influence the story's flow, perhaps by assigning difficult jobs or helping them out in tough situations.

The main characters are probably the trucker, who is the central human figure in the story, and the black dog. The trucker is the one who is presumably on the road, driving, and having some sort of experience related to the black dog. The black dog is important enough to be in the title, so it must have a significant role in the story, perhaps as a companion or a source of mystery for the trucker.

Since I don't know the story well, the main character is surely the little black dog. There might also be the dog's owner or some other animals it interacts with.

Since it's an Inuyasha fanfic, we can expect Inuyasha, Kagome, and the black dog to be central. Inuyasha, the half - demon with his sword Tessaiga, is always at the heart of any Inuyasha - related story. Kagome, the modern - day girl who travels back in time, has a crucial role. The black dog, which the title refers to, is likely to be a character with its own motives and backstory. And depending on the direction of the fanfic, other characters like Shippo, the young fox demon, could also be important.

Well, clearly the girl and the dog are the main characters. The girl could be a young child, a teenager or a young woman. The dog could be of any breed, like a Labrador, a Poodle or a mutt.

As we don't know the exact story, it's hard to say. But surely the boy and the dog are likely to be the main characters.
