  Pox 186 is an exceptionally small dwarf starburst galaxy hosting a stellar
mass of $\sim10^5$ M$_{\odot}$. Undetected in HI (M $ < 10^6$ M$_{\odot}$) from
deep 21 cm observations and with an [OIII]/[OII]\ (5007/3727) ratio of 18.3
$\pm$ 0.11, Pox~186 is a promising candidate Lyman continuum emitter. It may be
a possible analog of low-mass reionization-era galaxies. We present a spatially
resolved kinematic study of Pox 186 and identify two distinct ionized gas
components: a broad one with $\sigma > 400$ \kmps, and a narrow one with
$\sigma < 30$ \kmps. We find strikingly different morphologies between the two
components and direct evidence of outflows as seen in the high velocity gas.
Possible physical mechanisms driving the creation of high velocity gas seen in
[OIII] are discussed, from outflow geometry to turbulent mixing between a hot
(10$^6$ K) star-cluster wind and cooler (10$^4$ K) gas clouds. We find a modest
mass-outflow rate of 0.022 M$_{\odot}$ \ yr$^{-1}$ with a small mass loading
factor of 0.5, consistent with other low mass galaxies. Finally we compare the
mass-loading factor of Pox~186 with extrapolations from numerical simulations
and discuss possible reasons for the apparent discrepancy between them.
