I used to use inventory.overture.com for yahoo keywords, but that seems to be down.
You can use freekeywords.wordtracker.com, the keyword numbers aren't accurate representations of how many search yahoo, but the relative frequencies are.
Ie if you find that more people are searching for "dog training" than "stop dog aggression" in wordtracker, the same will probably be true in yahoo.
I hope that helps,
