A tightenable pet pad has a surface layer and one or more tightenable members provided on the surface layer. The tightenable member is the cord. Two end sections of the cord are joined to the surface layer and a middle section between the two end sections is free of joining to the surface layer. Therefore, in the case when the pet pad needs to be cleaned or replaced, the cords can be pulled upwardly to tight the pet pad into a pocket shape. Thus, the pet excrement is completely pocketed up and easily put into the trash bin.
