Perhaps the dragon has some connection to Harry's family. It could be a gift from an ancestor who had a special bond with dragons. In the wizarding world, there are often secrets in family histories that could lead to such a situation. Harry might find out about this connection as he delves deeper into his family's past, and that's how the dragon comes into his life.
Another possibility is that the dragon is an experiment gone wrong. In the wizarding world, there are always wizards messing around with magic they don't fully understand. A wizard could have been trying to create a new type of magical creature, and the result was this pet dragon that Harry ends up with. It could also be that the dragon was created as part of a dark magic experiment, but Harry manages to rescue it and make it his pet.
He probably feeds it a diet of magical creatures. Dragons might like to eat things like hippogriff chicks or giant spiders.
They could start with basic commands like 'sit' and 'come' using positive reinforcement. For example, giving the dragon a treat when it follows the command. Just like training a normal pet, but with magical treats perhaps.
There probably is. Fanfiction is a vast realm of creativity. In a story where Harry has a pet dragon, it could be a dragon egg that he stumbles upon during one of his escapades. He might raise it secretly at Hogwarts, with the help of his friends like Ron and Hermione. This dragon could become a symbol of his growing power and independence outside of the traditional magic he has been taught, and would surely lead to some exciting and unexpected plot twists in the fanfiction.
One idea could be a story where a young wizard discovers a dragon egg in the Forbidden Forest. He decides to secretly hatch it and raise the dragon as his pet. As the dragon grows, he has to constantly hide it from the Hogwarts professors, especially Hagrid who has his own ideas about magical creatures.
It could be Norbert, the dragon Hagrid once had. Since Norbert was a young dragon when we first saw it in the original story, it might have grown up and have a lot of stories to tell Harry.
In many fanfics, Harry being a Dragon Animagus can bring about really cool storylines. For example, it could add a whole new layer of power to his character. He might be able to use the strength and abilities of a dragon in battles against Voldemort and his Death Eaters. It also could change his relationships with other characters. Some might be in awe of his new form, while others could be afraid.
It might be a gift from a powerful dragon in Naruto's world. In some fanfictions, there are hidden dragons that see potential in Naruto and bestow upon him the power of dragon scales, which could be a symbol of strength and protection.
One possible plot could be that the dragon is a gift from a mysterious wizard. Harry at first is hesitant but soon grows attached to it. The dragon has special powers that draw the attention of both the good and bad in the wizarding world. Harry has to train the dragon and at the same time, deal with the political implications of having such a powerful creature. His friends are both in awe and a bit scared of the dragon, which also creates some tension in their relationships. And as the story progresses, the dragon becomes a key factor in a major battle against dark forces.
Yes, there are likely fanfics out there where Harry Potter has a pet dragon. Fanfiction writers often come up with creative and unique scenarios that deviate from the original story. They might explore how Harry would handle having a dragon as a pet, the challenges it would bring, and how it would interact with the wizarding world around him.
The Chinese dragon origin has multiple theories. One is that it originated from totems. Ancient tribes combined different animal features they respected, like the snake's body, the eagle's claws, etc., and gradually formed the concept of the dragon.
