More: My dog chrome had oral cancer and had a large tumor on his front canine tooth the size of a golf ball. He under went laser surgery and lost 4 front teeth. This year we found a marble size mass under his tongue and due believe it has returned. The surgery was very hard on him the first time and believe he will not make it thur another surgery. We are making him very happy and he is not bothered by his disability....he is a true fighter everyday. My family thanks you guys for making people aware of cancer in dog.
