Models of hierarchical galaxy formation predict that large numbers of low-mass, dark matter halos remain around galaxies today. These models predict an order of magnitude more halos than observed stellar satellites in the Local Group. One possible solution to this discrepancy is that the high-velocity clouds (HVCs) around the Milky Way may be associated with the excess dark matter halos and be the gaseous remnants of the galaxy formation process. If this is the case, then analogs to the HVCs should be visible in other groups. In this paper, we review the observations of HI clouds lacking stars around other galaxies and in groups and present early results from our HI survey of loose groups analogous to the Local Group and its implications for the nature of HVCs and galaxy formation.
