The total domination number of a graph G without isolated vertices is the minimum number of vertices that dominate all vertices in G. The total bondage number b"t(G) of G is the minimum number of edges whose removal enlarges the total domination number. This paper considers grid graphs. An (n,m)-grid graph G"n","m is defined as the cartesian product of two paths P"n and P"m. This paper determines the exact values of b"t(G"n","2) and b"t(G"n","3), and establishes some upper bounds of b"t(G"n","4).
