Willow is a 2 year old neopolitan mastiff. She is full bread from an established breader in Texas. Unfortunately, she has Addison's disease. She needs a prednisone tablet daily and a monthly injection of a long acting steroid (Percorten). Her medications are approximately $200 a month. She is a beautiful dog and weighs around 150lbs. She can live a normal life span with this disease as long as her owner is reliable about administering the Percorten every 28 days.
