Comparative Negligence

他自己遛狗不牵绳，和你意外把狗绳落掉，同样是疏忽。但是由于是你的狗去咬人家的狗，你的疏忽更多一些。那么在德州的民事伤害法里面，去找contributory  negligence 的逻辑吧。

Texas Negligence Laws Set a 51% Bar For Comparative Negligence

While Texas is a comparative fault state, our laws add another level of complexity to the rule. We use a modified comparative fault rule that limits an at-fault driver’s ability to recover damages. Called the 51% bar, this rule says you cannot receive compensation if you were 51% or more to blame for the crash. In other words, if you are more than 50% at fault, you lose and would get nothing.
