[Hunter] Able to turn Growl off?

I've been dungeoning on my hunter and I can't seem to find an option to turn the pet spell, Growl off. Any idea's?

 

if you use singular, there is setting to control pet taunt called PetAutoControlTaunt

[Setting, ReadOnly(false)]
[DefaultValue(true)]
[Category("Pets")]
[DisplayName("Taunt: Automatically Enable/Disable")]
[Description("True: Singular manages Taunt auto-cast; False: user controls Taunt Auto-Cast; ")]
public bool PetAutoControlTaunt { get; set; }
