  We performed a search for faint low surface brightness dwarf galaxies around
the major spiral galaxy M\,101 and in the large rectangular area within SGL =
[30 -- 80]$^{\circ}$, SGB =[10 -- 37]$^{\circ}$ spanning a chain of galaxies:
M\,63, M\,51, M\,101, and NGC\,6503, based on the data from DESI Legacy Imaging
Surveys. Six new supposed dwarf members of the complex were discovered. We
present a list of 25 prospective members of the M\,101 group and estimate the
total mass and the total-mass-to-$K$-band luminosity ratio of the group as
$(1.02\pm0.42)\times10^{12}~M_{\odot}$ and $(16.0\pm6.5)~M_{\odot}/L_{\odot}$,
respectively. We notice that the average dark mass-to-luminosity ratio in the
groups around M\,63, M\,51, and M\,101 is $(12\pm4)M_{\odot}/L_{\odot}$ that
almost an order of magnitude lower than the global cosmic ratio,
$(102\pm5)M_{\odot}/L_{\odot}$.
