You can get the TM28 (Dig) on Route 214 in the Ruin Maniac Cave in Pokemon Diamond.
There is no Pokemon mansion in sapphire.
He is not in Pokemon: Sapphire. You will not be able to find him. He is in Pokemon: Diamond, Pokemon: Pearl, and Pokemon: Platinum. You will definitely have trouble finding him in Pokemon: Sapphire.
you can't find it in Pokemon sapphire, but you can find it in Pokemon ruby. Hope this helped. :-)
Sandshrew learns Dig at level 30 in Pokemon X, Y, Omega Ruby, and Alpha Sapphire. It can be taught faster if you used the TM28.
