You cannot find Houndoom in Pokemon FireRed and will need to trade with Pokemon Emerald to get one. Houndoom itself can't be caught in Pokemon Emerald but it's pre-evolved form Houndour can be caught in the extended Safari Zone.
You get a houndour then evolve it i will update when I find out where to catch houndour
entei, suicune, and raikou those are the only one's i know of besides houndoom and houndour.
You find it when you talk to you mum at your house after beating the Elite Four
You can find wild Houndour in route 7 and in the Safari Zone. From there, evolve it into Houndoom.
Since you can't catch houndour your going to have to trade the Pokemon colosseum houndoom to firered breed it then hatch the egg to get houndour or you can get one from emerald's safari zone.
Trade Colloseum or evolve Houndour (to get by trading Houndoom from Colloseum and breeding).
you cant.you have to have Pokemon perl or action replay
The Pokemon Houndour is Fire
flint of the elite four has one.
you find one
sorry but you cant, houndoom is on the 2nd generation Pokemon and above, so that means he is not on fire red and leafgreen because they only have the 151 Pokemon on them from the original game.
Houndoom is a Johto pokemon and none of the Johto pokemon are in the first pokemon rumble.
