There's a fanfic I once heard about where it explored the submissive nature of some of the more timid magical creatures in Hogwarts' grounds. It was more of an ensemble piece that included creatures like the Nifflers. The author was really good at showing how these creatures interacted with the students and faculty in a way that emphasized their submissive qualities. But it's quite hard to find as it was a relatively old fanfic.
One popular 'submissive creature' themed Harry Potter fanfic might be 'The House - Elf's Tale'. It delves into the life of a house - elf in the wizarding world and shows their submissive nature in a detailed and somewhat sympathetic way. However, there are not a huge number of fanfics that specifically focus on this theme as it can be a bit of a niche area within the Harry Potter fanfic universe.
