Who are some breeders of pugs in Maryland?

I am looking for a pug, but cannot find an extensive list of breeders in Maryland.

because they happen to live there

check www.doggies.com

Your best bet is to attend a dog show to find a reputable breeder. You may pay a little more upfront, but remember that if you buy from a cheaper breeder that didn't screen for pug health you may pay more in the long run.
