Little dogs should never win dog fights with big dogs. Thats not real. Butt kicking every time I say.
My grandparents used to have a slightly oversized Yorkie, and lived on a large military base, right across the road from the sports field. My grandad would take him for a walk early in the morning, when the MP dogs were being walked, GREAT BIG German Shepard dogs, who could have swallowed him whole...he would always, without fail, go for them, it was hilrious. Luckily, my grandad was sturdy enough to hold him back...I fear it would have been one of the cases where the big dog would win, somehow....
