How do you catch a houndour in platinum version?

Answer 1

you have to get past a few other Pokemon in rout 7 until you find him.

Answer 2

It's in that really big patch of grass near the lake by Pastoria city. It won't come very often, so buy plenty of ultra balls. And if you're interested in a Riolu, when you get to Canalave city, GO TO IRON ISLAND when you get to the end of it, Riley will give you an egg, and it will hatch into Riolu. There's also a way to get Magmar. Fly to Floraroma town, then go over to the bridge by the valley windworks. turn to your left and surf all the way down the stream till you get to a spot called fuego ironworks. in the big patch of grass there are magnemites, floatzels, and MAGMARS! If you can find a male and a female you can breed them at the daycare to get a MAGBY! Trust me on this. A level 69 Lucario, level 59 Houndoom, level 70 Magmortar, and approximately 63 magby eggs in my PC box. Not to mention all the Hoen Region Starters, and 1 Arcanine. If you want to know how to get anymore rare Pokemon, just post it up here.
