Dog attacks

I'm of the mindset that as studies have suggested if cat was big enough, they'd kill you just as soon as look at you.

that is an interesting point (that and the picture above your post)

if you get big wild dogs you got wolves?
they hunt and kill in packs

if you get big wild cats you got mountain lions
they are solitary hunters

i couldnt find any real numbers on how they compare, both in numbers and fatal attacks, but i would rather tangle with a wolf then a mountain lion
