We have investigated the evolution of dust charge and ion flow at the sheath boundary for the collisional magnetized dusty plasma in the presence of non-Maxwellian electron distribution in account of source and sink terms. The set of governing fluid equations have been solved for given initial conditions, whereas the dust charging equation have been solved using Newton-Raphson method. We have extended the Bohm sheath condition for dusty plasma using Sagdeev potential approach and it is found that gas pressure, obliqueness of magnetic field, ion loss term, and choice of electron distribution affect the evolution of dust charge and flow of positive ions at the sheath boundary.
