Can you give an example of a 'big dog neverending story'?

One could be a story where a black dog is cursed to wander a haunted forest forever. Every night it howls, and every day it searches for a way to break the curse, but the story just goes on and on as it fails time and again.

Sure. The story of the universe's evolution can be considered a 'big moment neverending story'. From the Big Bang to the formation of stars, galaxies, and planets, and now to the potential future of the universe expanding forever or having other unknown fates. There are constantly new things being discovered and new theories emerging, making it a story full of big moments and seemingly never - ending.

The 'Lord of the Rings' universe. The main trilogy has an ending, but there are so many appendices, fan theories, and additional works that expand on the story. And the themes of good vs evil, power and corruption, are so universal that they can be explored endlessly. So it gives the impression of a neverending ending story as new interpretations and stories within the world keep emerging.

One could consider the story of Mickey Mouse as a 'Disney Neverending Story'. Mickey has been around for decades and his adventures keep evolving. There are countless cartoons, movies, and even theme park attractions based on him. His character is constantly in new situations, meeting new friends, and facing different challenges, making it seem like his story is neverending.

As of my knowledge, there isn't a big flying dog in 'The Neverending Story'. The story is filled with its own unique creatures and characters, and a big flying dog isn't one of them.

One example could be an old couple who met during World War II. They fell in love despite the chaos and hardships around them. Since then, they have built a family, faced financial difficulties, raised children, and now in their old age, they still sit on their porch every evening, reminiscing about their life together. Their story is neverending as they keep reliving and adding to their memories.

The concept of a haunted house where every time you think you've escaped, you find yourself back inside. It just keeps repeating, and the scares never stop. Each time you enter, there are new and more terrifying ghosts or events waiting for you.

Perhaps a serial podcast that doesn't have a set end - point. The creators keep coming up with new episodes based on the feedback and ideas they get from the listeners. It's free in the sense that it can go in any direction the creators and the audience inspire it to, making it a kind of free stream neverending story.

The story of Genghis Khan could be an example. His vast conquests, from Asia to Europe, created an empire that was huge. His military strategies are still studied today. Also, the mystery surrounding his death and the succession of his empire keep adding to the story. There are so many aspects to his story - his leadership style, the cultural exchange his empire brought about - that it feels like it has no end.

A shaggy dog story could be like this. A young boy heard that there was a special fish in a far - off lake. This fish was said to be able to grant wishes. So the boy walked for days to reach the lake. He got a boat and rowed to the middle of the lake. He fished for hours. Finally, he caught a fish. When he held it up, the fish just said 'I'm too tired to grant wishes today'. The long journey and the anticipation of a wish - granting fish, but a rather disappointing end.
