  We investigate the critical dynamics of a classical ferromagnet on the simple
cubic lattice with double-exchange interaction. Estimates for the dynamic
critical exponents $z$ and $\theta$ are obtained using short-time Monte Carlo
simulations. We also estimate the static critical exponents $\nu$ and $\beta$
studying the behavior of the samples at an early time. Our results are in good
agreement with available estimates and support the assertion that this model
and the classical Heisenberg model belong to the same universality class.
