An unmagnetized dusty plasma consisting of a negatively charged adiabatic dissipative dust fluid, Boltzmann distributed electrons, and ions has been considered, and a theoretical investigation of the basic properties of the dust-acoustic shock waves has been made by the reductive perturbation method. It has been found that the dust-acoustic shock waves exist associated with a negative potential only, and that the effect of the dust fluid temperature significantly modifies the basic properties (amplitude and width) of such shock potential structures.
