Make sure to use examples like movies where a person's relationship with their dog is shown as a deep emotional connection without crossing into romantic territory, unless specified. Maybe mention if there's a subgenre or a particular trend in certain cultures.
For cultural examples, maybe look at folklore, movies, books where humans and dogs form deep bonds. But is there a case where it's romanticized? Maybe in a metaphorical sense, like using the dog as a symbol of love or fidelity. But literal romantic relationships are rare. I should address that and perhaps include some fictional works where a human falls in love with an animal, including dogs.
Ethical considerations: animals can't consent, so even in fiction, such stories might be problematic. It's important to highlight the difference between anthropomorphism and reality.
Include how these storylines can highlight companionship, loyalty, and emotional support, which are real, but not romantic.
