A sheep is being credited for helping to save the life of its owner.  British resident Emma Turner tells the "Daily Mail" her pet sheep, Alfie, was the first one to detect that she had breast cancer.  Turner says one day Alfie just started butting her in the chest over and over.  A bruise eventually developed, and she subsequently discovered a lump on her breast.  It was eventually determined that Turner was in the early stages of breast cancer.  She has already undergone chemotherapy, and doctors say the tumor could have gone unnoticed for years had it not been for Alfie.  Turner adds that everyone at her hospital is "convinced" that Alfie saved her life.
