Gentle bulls don't exist in my experiences, they are all dangerous. Buck goats can be either way, I've had very good ones, and one so aggressive he was put down. The people who raised him played butting games, a big no no in raising goats, especially males.That woman was too comfortable with the Highland bull. The original story I read, which I cannot locate now, said he had always been friendly before that day, but hey, he's a bull and you can never predict what one will do. Big goat bucks would also make me cautious, like Leah's Mom said. All it takes is one knocking you off your feet, even if his intention was not to harm.
