User blog:Megadracosaurus/Where are the Dragons?

Before I saw HTTYD2, I wanted to refresh my knowlege on the Fandom, so I rewatched the first film, specials and episodes. However, I noticed something. In the films and specials, it Seems like everyone has a Dragon. In the TV Series, however, it looks like Toothless, Hookfang, Meatlug, Barf and Belch, Stormfly and Thornado are the Only trained Dragons. When the Dragons are locked up or banished, only the Dragons of the Teens were seen. And in "Smoke Gets In Your Eyes', Stoick said that five Dragons Weren't enough in order to defeat Dagur, while Berk should have a whole Army of them. So here's my question: What happened to all the other trained Dragons at the end of the first film?
