I would have thought herding or keeping large animals was quite dangerous, especially without modern technology. One of my wife's not-so-distant relatives was killed by a domestic pig.
Dangerous at times yes(like most of premodern life was) And cows, or rather bulls are for sure more dangerous than herding sheep. But most of the times it just meant sitting and watching.
Pigs are extremely dangerous for kids, but herding cows and goats is 100% something kids did. Source: I did it.
The village kids would get up, take the cows out to the road where the other cows also came, then together, a big group of kids and cows would head to a pasture and spend most of their day watching cows, playing games and messing about.
It was great.
Realistically the cows and goats took more care of the kids than the other way around.
