I'm generally not the type of guy who finds many things cute but being around a pitbull (and most dogs in general) has always made me act like a raging f*ggot. I'll instinctively get down on one knee and engage in all of that "Who's a good boy!?" bullsh*t without even thinking twice.
Bottom line : Dogs rule.
I'm sometimes in awe at the freakish strength, and athleticism of these dogs.
