Hunter EXP Bar for Pet?

[Scorcher24]

I have found this Addon:
http://wow.curse.com/downloads/wow-a...-info-bar.aspx

But it does not work for me. The Bar is not shown. I have fixed the "You are not a Hunter"-Problem myself, but it still does not work.
Is there any EXP-Bar for Pets which I can drag around the Screen?
I do not want to change the UI-Frames and use Pitbull or something like that... I like the Blizzard-UI and install minimalistic Addons only.
Thanks.
rya.
