When I slept over at my cousin's house for 4th of July, I brought my little Mocoa(Dachshund) to spend the night with them :D But my cousin also has a Chihuahua mix that is about... 5 Years while Mocoa is 4 years. And well, B.b(Chihuahua) never got close to another dog before, not even a girl doggy. (Oh yeah, Mocoa's neutered, B.b's not) So when they met, B.b barked of course, to protect his property. But Mocoa didn't do anything, since he's the quiet type. (Which I like) But soon, he didn't bark anymore and they looked at each other, occasionally sniffing each other's butt. But then, something weird happened, B.b tried to... You know, get on top of Mocoa. (Also, B.b is a boy and Mocoa is a boy also O_O) So yeah, could B.b have gotten confused? Since he hasn't met a girl dog before?
