We report on the first results of the Dwingeloo Obscured Galaxy Survey
(DOGS). This survey is a long-term project to systematically search t
he Northern Galactic Plane for 21-cm emission from galaxies hidden beh
ind the Milky Way. The detection of a previously unknown galaxy (which
we named Dwingeloo 1) early in the course of this survey suggests tha
t many more such galaxies are likely to be discovered.
