unfortunately the vanguard isnt active on test =[To test pet difficulty.. get on TC, tame one.... and set taming to say 104, feed it, and it will give you a message cannot bond yet. and keep setting it up by .1 until you no longer get the cannot bond message (you shouldn't get any message, cause it has not been a week yet)
