But no, the current "fight winner" system just seems unfair. Something about an itty-bitty poodle taking down a German Shepherd just doesn't sit well with me, you know? ;-)
You obviously have not seen a small dog in action. Those things are crazy. The result is a lot like watching Yoda fight, and I find this utterly plausible. Large dogs don't have much fight in them, it's just not a trait that makes one a good pet. If a big dog bites your leg off, it gets put down for being a danger to others. When a yappy terrier bites you in the ankle, this is just funny. So nobody attempts to stop those little dogs from trying.
