More: He is the smartest and most loyal dog I know. He is very special to me. Finding out a month ago he has tonsil cancer broke my heart. Any cancer is bad, but this particular type is very aggressive. He started taking chemo drug 3 weeks ago. His exam yesterday went well. We were told there is no regrowth. His health and well being is our priority. He is important part of the family. We will fight this battle with him.
