  Quenched and partially quenched chiral perturbation theory for vector mesons
is developed and is used to extract chiral loop correction to the $\rho$ meson
mass. Connections to fully quenched and totally unquenched chiral perturbation
theory results are discussed. It is also shown that (partially) quenched
perturbation theory for tensor mesons can be formulated analogously, and the
chiral corrections for tensor meson masses are directly proportional to their
counterparts in the vector meson sector. Utilizing this observation and
non-relativistic quark model, we point out that mass difference $(m_{a_2} - {3
\over 2} m_\rho)$ is ``quenching-insensitive'' in large-$N_c$ limit. This
quantity may be used for normalization of mass scale in lattice QCD
calculations.
