oh yeah, no doubt they are killers. We have some red bulls here that are quite dangerous and I try to avoid them. Is better to leave them in peace not disturbed. They "recognize" only their owners. They live like 7-8 months free on the mountains so they do not like "strangers".

This one in particular I know him that killed 3 dogs and a girl (tourist) passing by too close.

Hahaha nah I do not fear cows. Are quite friendly usually, I like them around, because they are good lawnmowers :) on my terrain. 
My mistake was that I forgot to put cords around the spaces where cows should not enter.
Cows are quite curious animals but they do not realize they are big volume and in small spaces can do unintended damages.
And they like to shit everywhere :)
