More: Izzy has been the most amazing dog. She has taught us how to live life to the fullest and most importantly, how to love. She has had cancer twice. The first time was three years ago when she was diagnosed with mast tumor cell. She went through chemotherapy with a prognosis of extending her life for another year. She now has liver cancer and we are taking any precious time we have left with this amazing girl, as time has been the greatest gift we have ever been given.
