The only time I‘ve ever seen a cow is when I went to my family’s cow farm in Munkwolstrup when I was four so forgive me if I‘m being crass, but what do you mean by „cows are more dangerous than they seem“
It’s incredibly ominous to say the least, considering I‘m already scared of horses.
So as with most dangerous animals, it’s often human error.
Thanks to selective breeding, domestic cows are very, VERY strong and hearding them mostly involves convincing them they are weak when in fact they can easily stomp you.
Now imagine you are a mummy cow and someone is walking through your field with an uncontrolled dog harassing your child. You try to warn it away and the owner comes over to intervene. Finally you push them both away only to discover you are as strong as the hulk and didn’t realise.
Accidents happen.
Not casting aspersions or anything it’s just as with anything, you are taking a risk when you don’t treat something with respect.
