More: Ralph, MD is a full-time resident dogtor at Children's Hospital Colorado. He has dedicated the last more than 7.5 years of his life to working with sick children. He works 40 hours a week motivating kids to walk after surgery, showing them how to take oral "medication" by drinking water from a syringe, he cheers them on as they ring the end-of-cancer-treatment bell, and lets parents hold his paw as their children reach the end of their lives. In February 2021, Ralph was diagnosed with t-cell lymphoma and has been working with kids in between radiation treatments and chemotherapy. He is the hero to thousands of children and families across the country. He is indeed a very good boy.
