They just look nice.
However, I have now learned that for the purposes of the law, a wolf breed is only legal if it is 3 generations from the wolf. Which sounds a bit of a weird way to judge it (especially when you have zero idea of where an animal comes from).
Surely (as suggested in the article) it would be easier to work on a %age of wolf DNA ?
Anyway bring back wolves. They can keep the deer epidemic under control.
