Its hard to tell from the pics but I don't think so. Like human dwarfs, dwarf cattle aren't just small, they're misshapen.
True.
Hard to tell from the photo, but a very prominent forehead in a young calf is an indicator.
Had neighbors that left their herd uncut, and un-sold for a few years, and the genetics started reaping the harvest... There were lots of dwarves over the fence. One crossing the fence into mine would have been a death sentence.
