My Puppy Rex, fight to beat cancer

My best friend and lil son Rex just sad news and kinda hard to enjoy and have fun right now. My Pup isn't looking well and possibly has a tumor that has been overlooked and to far off. Friday ill be heading to a cancer group vet which will do consulation for $180 and radiation therapy going from 1000 to 2000. Anything that can be done to help would be amazing. I hate that it has to be so far down the week that its taking forever. He is weak and getting skinny swollen under his tonsils making it hard for him to drink and eat. The spread of this sucks and I hope anything can help. Thank you.
