I wouldn't say "totally harmless", don't get me wrong it isn't like I am going to be scared of a sheep in the way I might some kind of large predator but males will charge you and ram the shit out of you and if they have horns that has the potential to be nasty.
We used to have a sheep that loved being stroked and would head butt you in appreciation, the only problem is the more he enjoyed it the more of a run up he got each time, harder and harder. When you are a small kid a sheep ramming the shit out of you literally sends you flying.
One time I was watching one of those youtube videos of stupid drivers dash cam compilations. This one driver is driving in the countryside, and flying over these hills at 90mph. He flies over one hill, goes airborn, and crashes into a fence, and then hit a cow.
The cow goes down, and suddenly this OTHER cow comes running around from out of nowhere. I thought it was funny at the time, because the cow had this real aura about him like he was running up like "STEVE!!! STEVE ARE YOU OK???"
I was just imagining that's what the cow was doing, and it was funny to me.
Only for me to tell this same story years later, and get told "Actually, cows are very empathetic, and social creatures. That cow WAS running up to check on his friend. That's what was happening for real."
And I think that's kind of cool. A cow can be your friend.
Yeah. They are ridiculously social creatures and I absolutely saw them mourning a friend.
(But they can be assholes as well. Towards humans,but also between themselves. One of the funniest childhood memories I have is a cow intentionally toppling another cow (T-boned crash basically) and then shitting in its face. Comment of the carer: "yeah,she does that when her peers piss her off. She tried to do that with me as well,but missed and headbutted into a wall. See the missing brick? That was her")
I'm a bit biased, but this dog has saved my life countless times. He learned how to detect my seizures, on his own, and I haven't collapsed or injured myself from a seizure since. This is Avalanche. He's by my side 24/7 and since I'm a cosplayer, he is too!
