Maybe. Or Scottish Highland--there used to be a couple herds of that breed near where we live. They're basically big fuzzballs (well, from the road, at any rate; up close they're probably kind of scuzzy) with gigantic horns.
I live near Dallas, so you can understand why I thought that. Is that Little Dude or is it his cousin the herdsman?
