You can find Houndour on route 7 at night.
go to route 214 below veilstone and run around in the grass
Houndour is a version-exclusive Pokémon, and thus it can only be caught in Pokémon X.
If you want one, trading or transfering is required.
You can catch a Houndour in the Altering Cave in Pokemon FireRed.
You get a houndour then evolve it i will update when I find out where to catch houndour
Only in Pokémon X. If you wish to own a Houndour in the Y version you must trade with someone that has one. Try to catch an Electrike and trade it for a Houndour at the GTS, since it is its exclusve Y version counterpart there may be people interested in said trade.
You cannot catch houndour in Pokemon leafgreen either get one from Pokemon emerald or Pokemon colosseum.
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.
Only Pokemon colosseum can get a houndour although you actually get a houndoom just breed it to get houndour in leafgreen.
