  We propose a novel model which extends the Standard Model (SM) by introducing
a $SU(2)_D$ gauge symmetry. In this model, a dark $SU(2)_D$ Higgs doublet and a
Higgs bi-doublet can contribute to the muon $g-2$ anomaly and the $W$ boson
mass, remaining in tune with the recent experimental results. At the same time,
the isospin charged gauge boson of $SU(2)_D$ becomes a plausible candidate for
Dark Matter(DM). We find that the resulting parameter space can fit the muon
$g-2$, the $W$ boson mass and the DM constraints simultaneously.
