In Patch 5.0.4 The Hunter Pet Bar always appears when you summon a pet, this is intended. If your like me and many other hunters you might use another addon to handle the pat action bar, and having 2 pet bars is clutter, especially when you use addons to have more hot-bars.
So this simple thing just hides the standard blizzard pet hotbar. No /commands or UI.
