You mean you would rather pet a wild cow than a cow that was meant to be pet?

I don't see the big deal, go to your local fair and they will have cows that are meant to be pet. I've never heard of a wild cow, but wild animals are not meant to be pet.

edit: What cow is not a dairy cow? You have the male bull and the dairy cow that produces milk. I don't think there are much variations in cow selection.
