There's a fanfic where they are wolves and it focuses on their pack dynamics. Harry is the young and eager wolf, Severus is the wise and experienced one, and Draco is the proud and somewhat rebellious wolf. The story delves into how they protect their territory from dark forces in the wizarding world while also dealing with their internal power struggles.
One common theme is the exploration of their changed relationships. Normally at odds, as wolves they have to find new ways to interact. For example, Draco's superiority complex might be challenged when he realizes Harry and Severus have different strengths as wolves.
One common theme is the struggle for acceptance. Since they are wolves in a world mainly populated by humans (wizards), they often face prejudice or misunderstanding. Another theme is the discovery of their true nature. They have to come to terms with being wolves and all that entails.
In some fanfictions, Draco and Severus might be portrayed as hurting Harry for various reasons. It could be due to the long - standing rivalry between Draco and Harry, with Draco's family's pure - blood ideology fueling his actions. Severus, on the other hand, has a complex relationship with Harry. His actions that seem to 'hurt' Harry could be misinterpreted. For example, his strictness in Potions class might be seen as a form of harm, but it could also be his way of trying to protect Harry in a convoluted way.
I'm not a big fan of this sort of fanfiction concept as it goes against the original relationships in the Harry Potter series. However, in the vast world of fanfiction, there might be such works out there. You can try searching on popular fanfiction websites like Archive of Our Own (AO3) or Fanfiction.net.
They might hurt Harry physically in some fanfictions. For example, in a fight scene where Draco uses dark magic he's not supposed to and Severus doesn't stop him in time. Another way could be emotionally. Draco could spread false rumors about Harry, which Severus, as a teacher, fails to address properly, leading to Harry's isolation and emotional distress.
One popular 'Harry and Severus are wolves' fanfiction is 'The Wolf's Bond'. It explores their relationship in a unique way as they navigate the challenges of being wolves in the wizarding world. Another one could be 'Wolves of Hogwarts' which delves into their pack dynamics and how it affects the events at Hogwarts.
In this scenario, Severus' character experiences a significant transformation. He has to shed his cold exterior to a large extent. He becomes a father figure, which means he has to be there for the boys emotionally. He starts to show emotions more openly, whether it's pride when they do well in their studies or worry when they are in danger. His sense of loyalty also shifts. Before, it was mainly towards certain people or causes, but now his loyalty is first and foremost to Harry and Draco. This new - found loyalty makes him a more rounded and likable character in the fanfiction, as he is no longer just the brooding potions master but a loving and dedicated father.
Perhaps in the fanfiction, Draco and Severus leave Harry because they are forced to by some external dark force. This could lead to Harry having to face new challenges alone, while Draco and Severus struggle against this force in their own way. They could end up being spies or trying to find a way to defeat the dark power from afar.
One common theme is the exploration of unexpected relationships. It challenges the traditional enmities between the characters in the original series. Another theme could be the struggle against the wizarding society's norms.
