A set S of vertices in a graph G = (V;E) is called a total k-distance dominating set if every vertex in V is within distance k of a vertex in S. A graph G is total k-distance domination-critical if k t (G 􀀀 x) < k t (G) for any vertex x 2 V (G). In this paper, we investigate some results on total k-distance domination-critical of graphs.
