I assume that you've simply added a premaid release to your database without even getting in touch what that guy/girl actually scripted there. And probably, it was a Roc pet.
Do yourself a favor and learn it. These are the basics of adding stuff to your database.
Check your Wolf's level list. Hint: 'COS_P_WOLF_%'
Find the respective table, the lines and how they were started and expanded.
You might figure out how this works getting a pet from Lv1 to Lv140 or lower/higher.
