I have the same issue/question and found this helps:
https://docs. google. com/spreadsheet/ccc?key=0Aj-3f0NjyQ5qdFZZaUJXaGlmaGEtSHVoT1U0dTROdEE#gid=2 (remove spaces, I can't post links yet). It's not ideal, you can't search easily, but you can see in one look, by the colors, which pet has a certain attack type. If anyone found anything better, please let me know
