Horses
Friesian horse, stallions/colts meet each other in the field
Assuming this is the first time they’ve met, that is fairly mild for a pair of stallions being introduced. I expected a little more in the way of fireworks.
For those unfamiliar with horses, this was done correctly: Neither horse was shod and there was lots of room for them to get away from each other if needed. While stallions do play rough, it is healthier for them to be together – they are happier with company.
