Motivated by the recent experiment [Takafumi Tomita \emph{et al.}, Sci. Adv.
{\bf 3}, (2017)], we study the dynamics of interacting bosons in a
two-dimensional optical lattice with local dissipation. Together with the
Gutzwiller mean-field theory for density matrices and Lindblad master equation,
we show how the onsite interaction between bosons affects the particle loss for
various strengths of dissipation. For moderate dissipation, the trend in
particle loss differs significantly near the superfluid-Mott boundary than the
deep superfluid regime. While the loss is suppressed for stronger dissipation
in the deep superfluid regime, revealing the typical quantum Zeno effect, the
loss near the phase boundary shows non-monotonic dependence on the dissipation
strength. We furthermore show that close to the phase boundary, the long-time
dynamics is well contrasted with the dissipative dynamics deep into the
superfluid regime. Thus the loss of particle due to dissipation may act as a
probe to differentiate strongly-correlated superfluid regime from its
weakly-correlated counterpart.Comment: 7 pages, 5 figure
