Or you could not get a Poochyena, or you could just use teleport to tire Poochyena out, OR, use confusion to get rocks or branches or something of the sort to help weaken Poochyena. But using confusion on Poochyena himself/herself? Yeah, not going to work. Then again, it's up to Frostbite to decide if you catch Poochyena or not. XD
