How do you use your pet?

When you go onto special power (the green bit) if it has one or more pawprints then try tapping the center part once.
If rons is a sort of candle stick thing then try standing in front of a pet tube if that doesnt work use freeplay and selet hermione (only works if you have completed that chapter/mission)

Press A. Then press X to go back to Ron/Hermione

You touch the green circle on the spell pad and the you tap the big circle in the middle.

Click on the sign with a paw and that will work. P.s. Good luck

When you click the green button on the spell wheel, when you've selected ron or hermione, press A. When you want to dig press Y on the spots with the paw prints.

Well, you must press A to transform and X to untransform, simple.

You hold c on the nunchuck then with either the left or right analog stick select the green circle
