While dragons tend to have a reputation of being Nigh Invulnerable, sometimes this isn't enough: Not all dragons are clad in titanium-strength scales, or sometimes they need extra protection from dragon-killing weapons that would easily pierce through their normal scaly hides.
When this is the case, it's time for even the dragons to suit up in a layer of crafted blacksmith armor. Not only may it shield a potential weak spot (like a single missing scale), it looks cool to wear, doubly so if it's silver or gold in color.
Dragon armor is more common if a Dragon Rider is also involved, as the armor provides places to affix a saddle and harness to. Can also occur if the dragon is presented like an ordinary Beast of Battle, as the fantasy equivalent of medieval war horses.

- The Hobbit has Smaug the dragon, who encrusted his soft underbelly with diamonds and other gemstones.

Of course, nothing stops you from wearing armour before this, or even fluffing this circle as more traditional metal armor.
