Adventure might also be a common theme. They could go on various adventures together, solving problems and having exciting experiences in the Pound Puppies world. Maybe they rescue other puppies or discover new places in the fanfics.
I'm not sure about specific Pound Puppies Lucky x Dot Lemon fanfic. You could try searching on fanfiction platforms like FanFiction.net or Archive of Our Own. They usually have a wide variety of fanfictions for different fandoms.
One common theme could be friendship. They might explore how Lucky and Cookie's friendship develops over time. Another theme could be adventure, with them going on quests together in the Pound Puppies world.
I'm not sure of specific Pound Puppies Lucky x Cookie fanfictions off the top of my head. But you can try searching on fanfiction websites like FanFiction.net or Archive of Our Own. They usually have a wide variety of fan - made stories for different pairings.
As mentioned before, 'lemon' content is inappropriate. However, if we were to hypothetically consider just the general Pound Puppies fanfiction aspects, it might have detailed characterizations of the Pound Puppies themselves, their personalities, and their adventures in the pound or with their new owners. But again, 'lemon' content should not be part of it.
One common theme could be friendship. They might go through various adventures together and their friendship deepens. Another theme could be mutual support, where they help each other out in difficult situations.
The appeal lies in their cute relationship. They are both such endearing characters, and seeing their love develop in fanfiction is really charming.
Love might also be a theme, not necessarily in a romantic way, but a love that comes from a deep understanding and connection. They could have a story where they show unconditional love for each other, facing difficulties together and always being there for one another.
If we were to consider acceptable themes within this rather unusual concept, perhaps themes about the care and anticipation before the puppies are born could be one. For example, how the mother dog prepares a safe space for her future puppies.
A common theme is friendship exploration. Since Konata and Miyuki have different personalities, fanfics often delve into how their friendship develops and deepens. It could be about them getting to know each other better through shared hobbies like anime and manga.
I'm sorry, but 'lemon' in fanfiction often refers to inappropriate or adult - themed content. So I can't recommend such Pound Puppies fanfiction.
