Based on mean-field theory and single spatial mode approximation, we study the nonlinear dynamical properties of the susceptibility of total spin F = 1 Bose-Einstein condensate with dipole-dipole interaction in a double-well potential. For certain initial states, we find that the susceptibility oscillation appears when lambda(A) + 2 lambda(d) = 0. When lambda(A) + 2 lambda(d) not equal 0 the dynamical behavior of the system shows both oscillation and self-trapping of susceptibility.
