Good find. I have a pitbull and a chihuahua...my pitbull is by FAR sweeter. The chihuahua is a baby / bitch. My pit is good as a watch dog but I'm still trying to guess if she'd actually attack anyone. She's tough when she needs to be, but I think if you run towards her, she'd back off. I mean, she got her ass kicked my a cat last summer.
Ohhh I just love her. I have the bestest dog. =)
