Question from the comments

This was commented on one of my posts about my Ghost Saber and the red she becomes.

I know that the "red" appearance comes from the Beatial Wrath. Did your Ghost Saber learn this over time, or did have the ability when he spawned? I have a one and she doesn't have the ability.

Bestial Wrath is a talent learned skill in the Beast Mastery Tree.

Here's the tooltip:

Bestial Wrath
10% of base Mana 100 yd range
Instant cast 2 min cooldown

Send your pet into a rage causing 50% additional damage for 18 sec. While enraged, the beast does not feel pity or remorse or fear and it cannot be stopped unless killed.

The 41 point BM talent is called the Beast Within, which makes the Hunter Big Red and Mean. It reduces your mana costs and gives you the same immunity to crowd control as your pet.

If you look to the side over to the left you'll see a link to the Beast Mastery Hunter blog called Big Red Kitty. He has tons more info on this spec.
