Input: CONTEXT: The wiki states that the smaller portals were inter-dimensional "wounds" that would close/collapse quickly after forming, and that only the Demogorgon could make them because they took a lot of energy to create. Presumably the "demo dogs" are too weak to make portals like this, which is why they dig the tunnels instead.  <sep>  Q: Why is the portal so hard to close in Stranger Things 2, when the monster opened many in the first season?

Yes
