The effect of the dust charge-to-mass ratio on the soliton solution is discussed. The Sagdeev potential is derived analytically with constant dust charge and then calculated numerically by taking the dust charge variation into account. We show that the dust charge-to-mass ratio plays an important role in the soliton properties. The soliton solutions are comprised of two branches. One branch is sub-Alfvenic and the soliton velocity is obviously smaller than the Alfven speed. The other branch is super-Alfvenic and the soliton velocity is very close to or greater than the Alfven speed. Both compressive and rarefactive solitons can exist. For the sub-Alfvenic branch  the rarefactive soliton is bell-shaped and it is much narrower than the compressive one. However  for the super-Alfvenic branch  the compressive soliton is bell-shaped and narrower  and the rarefactive one is broadened. When the charge-to-mass ratio of the dust grains is sufficiently high  the width of the rarefactive soliton  in the super-Alfvenic branch  will broaden extremely and a electron depletion will be observed. It is also shown that the bell-shaped soliton can transition to a cusped structure when the velocity is sufficiently high.
