Defog doesn't exist as a TM, nevertheless it does exist as a HM in Diamond, Pearl and Platinum. Getting the HM depends on the version of your game. In Pokemon Diamond and Pearl, you get the HM from an NPC when you enter the Great Marsh. You will need the Fen Badge from the Pastoria City's Gym in order to use it outside of combat. In Pokemon Platinum, you will find the HM deep inside Solaceon Ruins. You will need the Relic Badge from the Hearthome City's Gym to use it outside of combat.
there is no defog in pokemon black/white
in the great marsh
There is no way for you to get Defog in Pokémon SoulSilver, there is no Defog HM or TM in "SoulSilver" and there are no Pokémon that naturally learn Defog, the only way for you to get a Pokémon to know Defog in "Pokémon SoulSilver" is to trade the Pokémon over to "Diamond, Pearl or Platinum" and teach it Defog and then trade it back over to SoulSilver.

there is no TM defog sorry, unless u are talking about an other one i don't know.
I would say Fly, Steel Wing, Psychic (TM), and Confusion (if you have Diamond/Pearl, you might want Defog).
in the safari zone in pearl/diamond right when u enter u see a man talk 2 him and he will give u the hm
Good creativity. But dig can not be used In that Pokemon sadly although defog can be used --------- Even though Dig is a TM but not a HM (i take it you play R/S/E?) it can be used as a HM to crumble the middle section of the top of the first room in Ancient Tomb.
go to the ruins and when in the first room go into the back and read the sign it may look like nonsense but it's unown lettering
Return, Avalanche, Trick Room,if you mean TMs they are: cut, fly, surf, strength, defog, rock smash, waterfall, rock climb.
