My dog has been missing since 9/19/2021 I wanted to know how do I go about finding her…I posted her picture & videos on my social media accounts & I need help finding her I believe this guy in my building that lives on my floor took her & sold her

You can make a police report And check with the shelters

If your dog has a chip. It can help locate her

Unfortunately, it's a civil matter, police can't really do anything. If you can get proof you can go to courthouse & file for a replevin, pets are considered property in the state of MD. I know all this because our dog was stolen and this was the process for it. It's very unfortunate and I hope you get your dog back.
