More: Charlie is a hilarious, bright, loving dog who has moved all over the country with his people, walked down the wedding aisle with his parents, helped welcome home two babies, loves alpine lakes, snow blowers, and down comforters. A neighbor once described him as the John Wayne of bird dogs. He was recently diagnosed with osteosarcoma and if his handsome, smiling face can help bring research funding for canine cancer research, the world really will be a better place.
