I wonder that as well. I wish I knew where my dogs came from, not only for health reasons but also just to know those little facts about their history. My male was an adult when we adopted him and the only thing the previous owners had said was that he was part wolf. I don't think he is, though. Regardless, they took good care of him because he was well mannered and healthy when we got him. But little girl is a mystery! Who knows. Lol.
