Thank you for all your support everyone.

I am just glad that no one thought I had an issue with someone who does have a deep fear of dogs. A phobia. For whatever reason. I don't understand it but then again but then again it is no different than people who have a fear of snakes, spiders etc. While I might not like those type of pets, I know there are people that do, just like my dog.
I dunno - they've been together for about 3 years total, and I never got a malicious vibe out of her. Even her present reaction with Keegan, isn't malicious and doesn't SEEM manipulative. No one pays her any mind when she acts the way she does. Unlike my dad's cousin's wife, who can't stand dogs, she CONSTANTLY wipes her hands on her pants when Keegan is around and walks around with this upturned nose like she stepped in a big pile of rotting poo. Now THAT action makes me want to PUSH her in a pile of rotting Poo.
New Wife - doesn't give me that vibe. I'll keep you all posted on how the situation progresses, and again I appreciate ALLLLLLL the insight.
AND the compliments on my Big Red Dog.
