It might imply that the fanfiction is taking Draco out of his normal or expected context. So, instead of following the canon storyline, the fanfiction is 'dragging' him into new and uncharted territories, like making him interact with characters he would never meet in the original story or putting him in situations that force him to grow or change in ways not seen in the original series.
Relationships also play a big role. The collar can be a catalyst for new relationships or a strain on existing ones. For example, it might change how Draco interacts with his friends, family, or enemies in Hogwarts. It can create interesting scenarios where characters have to re - think their feelings towards Draco because of this new element in his life.
You can start by looking on major fanfiction platforms such as Archive of Our Own (AO3). It has a large collection of Harry Potter - related fanfictions, and you can easily search for 'dragged Draco' within the site. Another option is Fanfiction.net, which also has a good number of such works.

I'm not very familiar with this specific type of fanfiction. However, you can try searching on popular fanfiction websites like FanFiction.net or Archive of Our Own. There might be some works that match this description, but it could also be a relatively niche concept.
Another example is that Draco could be dragged into a time - travel adventure in fanfiction. He might be unwillingly pulled into a situation where he has to travel back in time and interact with the founders of Hogwarts. This would be a huge departure from his normal life at Hogwarts and would force him to adapt to a very different environment.
One possibility could be that Draco is being forced into a situation against his will. Maybe he's being dragged behind in a magical chase where his enemies are after him, and his friends or foes are pulling him along as they flee or pursue. It could also be part of a prank gone wrong in the wizarding world, where he ends up being dragged behind someone's magical transportation device.
To write 'dragged draco slave fanfiction', start with creating an interesting setting. Maybe it's a post - war Hogwarts where there are new power dynamics. Decide on the rules and limitations of Draco's 'slavery' situation. Is it physical slavery or more of a mental/emotional one? Develop other characters around him. For example, who will be the one to 'drag' him into this? Will there be a character who tries to rescue him? Also, pay attention to your writing style. Make it engaging so that readers will be interested in this rather unique take on the character.
His character could develop through the experience of being dragged behind. He might become more defiant, vowing to never be in such a powerless position again. For example, he could start training harder in magic to protect himself.
