Bullion is a Welsh pony that we figure is over 25 years old. He's a crotchety old cuss and doesn't let any other animals around during feeding times except the chickens. They aren't afraid of him and are quick enough to get out if the way when he starts stomping.
He can't stand goats but he seems to be ok with the one sheep that my daughter has.
With all his faults, he's still a pretty good old boy. He doesn't mind getting saddled up and led around for the granddaughters.
