The dynamical critical behaviour of the

Ising spin glass is investigated at the damage-spreading threshold

. The dynamical critical exponent z is observed as

for d = 2 and

for d = 3 . The fractal dimensions of the damage cluster are estimated as

for the 2D Ising spin glass and

for the 3D system, which satisfy the equation

within the error bar.
