Beavers attack dog!

[Tobi]

Attacks by cows aren't always about them protecting their young. The Bullocks are very frisky, and very heavy and dangerous and will often charge and surround a person just for the sheer fun of it. They most likely don't mean to kill anyone, but they are aggressive in a sense in that they will make a bee-line for someone to harass them.
People (and dogs) get killed because they get knocked down and trampled on.

I can't believe that people are choosing to ignore warning signs about the Beavers! How thoughtless.
