"Hvorfor er du bange?"

Translation: Why are you afraid?

[LucBE]

How would one say "What are you afraid of?"

[btwillbethere]

'Hvad er du bange for?' :)

[LucBE]

That was unexpected... :-)

So Danish uses the English expression, and not the Dutch or the German ("Waarvoor ben je bang"/"Wovor hast du Angst" = Hvad er du bange for, vs. "Waarom ben je bang"/"Warum hast du Angst" = Hvorfor er du bange.)

[Fred-3-CMY]

In German, you can also say "wovor ist dir bange?", but it sounds a little outdated or stilted - still usable, though.

[Pat211087]

Why are you frightened? Should also be accepted.

[mackelpr]

Because you hugged me.

[margo603533]

Why are you afraid / Why are you frightened

I would say these are interchangeable

[Milaena]

How would you say 'a scared animal?' Do you add a 't' suffix to bange or not?

[RyagonIV]

Bange is invariant, so it would be "et bange dyr".
