Love this and other vet shows. Learn so much and find many episodes moving. However more and more I am wondering why Charles has so much air time. Has a lot to say but often gets in the way. The more I see of his personal life the less I want to know. Does he have a medical background? College may e a good option for him. Wish every one the best. Just Googled Charles and learned he graduated from college an interned with Sidney Pollack. He is a producer on the show. Perhaps his best work is behind the camera.
