Dahlia is a short blooming flower when cut.

This though suggests a problem in the roots, possibly root rot from over watering and no drainage. https://www.gardeningknowhow.com/ornamental/bulbs/dahlia/dahlia-flower-diseases.htm

I suggest you take it out of the pot and put it in clean dry soil.  Send me a picture of the root/tuber when it is washed off. 

Thank you for writing.
