You can find a Houndoom in diamond, you find it in route 214 or 215 using the poke radar. well hope this helped.
Person on top of me, YOUR SOO wrong. You can't get it in diamond you have to have the national and migrate the region houndour is in. then evolve houndour to houndoom. Do this only if you have national
In Platinum version Houndoom learns Flamethrower at level 48. in diamond and pearl Houndoom also learns it at level 48.
You can find wild Houndour in route 7 and in the Safari Zone. From there, evolve it into Houndoom.
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.
Breed a female Houndoom with a compatible Pokemon and hatch the Egg. I got the information from Pokemon.marriland.com
Trade Colloseum or evolve Houndour (to get by trading Houndoom from Colloseum and breeding).
You get a houndour then evolve it i will update when I find out where to catch houndour
