Houndour Catch

[Lina]

Hello

How can I catch a houndour? I joined Team Aqua, I know it can be trapped in the Magma Base after defeating the boss. But it didn't appear there. Does it have to be a specific time and a specific weather? I've already searched here in the forum, but I didn't really get any smarter, to be honest. I hope that somehow I can be helped. Definitely wants to have Houndour as it's my favorite Firetype.
thanks in advance

Strange, it should be there. You can find Houndour elsewhere but that's way later in the game.
