Re: voice pitch & dominance perception
Praise must be tailored to the individual dog. If you use high squeaky praise with my dog, he will get so over-excited feeding off that silly energy, he'll "lose the lesson" that you were trying to teach him.
My dog is praised in a low, deep, soothing voice. Imagine g-e-n-t-l-y stroking his head with your voice: "Fiiiiiinnnne.....fiiiiinnnne..."
As far as dominance goes, I have noticed the same thing he mentions above: High pitched means my dog ignores it. (I have a PUSHY, dominant dog) Normal voice or deeper gets his attention: "Whoa, Momma.. sorry, I'll pay better attention!"
This may not matter to some dogs who don't have a dominance agenda. Tone may also not matter to dogs who don't care if they please their handlers. But, for some dogs-- like mine (dominant/pushy, but wants to please)-- tone DOES affect his response.
