When I'm trying to train my pet at Pet Master Ellan, I drag the pet training item into the window, but where do I drag the pet from? I've tried targeting his portrait and dragging it, or dragging other things.

This is probably really obvious but it's just escaping me.

Before you train it, put it into your bag 1st..

Press "P" on your keyboard, this should open the pet interface.. click on the pet you want, and click on a button on the right saying "Put pet into bag" or something like that.. it's the 4th button from top if i remember correctly..

After that, continue with the steps you've written up there ↑↑↑

thank you!
