kind thoughts. He is a mixed breed as we rescued him. He is part Sharpai, Golden Retriever and Sherman Shepard and 6 years old. BTW the tumor is benign, but it will keep growing and since its so close to his brain it would eventually kill him. Radiation will shut it off from growing and hope to size it down in half and make him be able to breath through his nose and not so much through his mouth. The vet said we should know in about 2 weeks how much this is working for him.
