I have a dahlia that was doing well and today I noticed black spots on its leaves. Any idea what it is? And what to do? Thanks!

This is an automatic reminder regarding r/dahlias Rule 3:
When reasonable*, posters should make a good-faith effort to identify which variety/varieties are shown in their photo(s). If you don’t know for certain, please say so. Someone will usually know!
*Common-sense exceptions to this rule will be honored, such as if the photo does not contain a blossom, or if your photo contains large volumes (such as in wide field shots).
If you’ve already done this, thank you! No further action required.
If not, please add a reply to this comment and confirm if you know the name of your dahlia variety/varieties shown in the photo(s). Alternately, if you’re uncertain of the variety name(s), it’s ok to say that, too.

Have you checked closely for pests? Check the underside of the leaves as well. The picture isn’t large or clear enough of the affected areas to really say for sure, but I may see a few thrips on the brown spots.
