Well, as we talked in chat the other nite, Keegan can get freaky with men who have beards. I don't know why. I have had her since she was 6 weeks old. My mom's cousin tried to sit on the floor with her and she wouldn't get near him she just kept barking at him, until I threw him the tennis ball, then she had a new best friend!
I think part of Keegan's 'attitude' is she has only been socialized with a certain amt of people. Family, neighbors, etc. She is pretty good at the dog park, but she also sticks to my side pretty much.
To answer the question about if he can sense that your friends brother is an a$$ DEFINATELY
Kylie didn't like my friend's boyfriend from the beginning b/c I think she could sense what a jerk he is. When I first got her she was pretty shy around strangers/men, then a couple months ago, when I had my high speed internet installed the guy that was installing it, I thought was a pretty nice guy, but Kylie was over sitting beside him and putting her paws up on his leg and meowing! She never ever does that!
Then I found out that he and his wife have 5 dogs! I think she could sense that he was a good guy and an animal lover!!
