We present a search for neutral hydrogen (HI) emission from optically identified dwarf galaxy candidates in the larger M81 group area. Of 136 candidates, 68 galaxies have been detected (this corresponds to a detection rate of tex2html_wrap_inline500 49%). Most of the detected galaxies are background objects and fail to be classified as dwarfs. Many known dwarfs in the M81 group have been detected, but no new members have been discovered.
