Mostly? Mostly what? Yes, there are works where dragons are portrayed as intelligent beings. However, there are very few such works. These are rare exceptions that are not significant compared to the generally accepted canons.
People eat, use the restroom, and sleep not because they are intelligent, but because these actions are necessary. But, I hope it is beyond dispute that, in addition to physiological needs, they are engaged in many other things?
This is not applicable to dragons, which, like any animal that we can observe in the real world, are only concerned with satisfying the aforementioned needs. Of course, even the dullest of these reptiles, due to their somewhat magical nature, is considered more intelligent than many animals. Approximately at the level of a dog or even a mentally challenged child. But this "intelligence" only serves to optimize the satisfaction of those needs.
Humans are intelligent. Sheep, mushrooms, and vegetables are not. If we are not talking strictly about biological classification, then humans cannot be easily placed on the same level as speechless creatures.
that is exactly applicable to dragons, what makes you think it isn't?
And the discussion about intelligence is already entering the realm of philosophy, where there is no single opinion and even less evidence. It's just that everyone has their own opinion)
speechless creatures? Some communicate through movements, dances, and behavior. What's wrong with that? And for them, our words are utter nonsense; they wonder why we invented them.
Maybe some communicate through thoughts, but we don't know that.
Or they make sounds, but we cannot hear them, detect them, or even have any basis for their existence.

P.S. I have an achievement there, where it says that dragons are less "broken" than humans, not "broken," but "developed." Otherwise, due to my T9, it might not be understood
