Sheep or pig? The mangalitsa was bred from hardy Hungarian pigs (Bakonyi and Szalontai) crossed with the Šumadijas from Serbian. It is totally swine. It produces less meat then the naked pink pigs you're used to seeing, so it has become quite rare.
I have became infatuated with these fellas. Even wanting one, but I guess kitties and puppies with have to do =)
