Saving my pups life

One of the most important beings in my life needs surgery or he will have to be put down. I want what's best for my pup, he's still young, he's a good boy and very lovable. I am at a loss for words, I'm not even really sure what to write. I just want to help him live a long and happy life. I don't want him to be in this kind of pain.

Anything will help and it will be greatly appreciated by myself, my family, and the people that love Chief.
