Help our small dog with a large tumor.

Our dog Max is 7 years old, and he recently got a large tumor, after years of being a healthy dog, near his right rib. He was always a very happy, and healthy dog for a while, and seeing a large tumor was very sad and scary for us. After visiting vets to help treat his tumor, we found out that we need a CT scan, a surgery, and possibly further treatment after that. The surgery alone will cost $2000+, and the CT scan will be at least another $1500, if not more. Max and his family would love any amount of help to pay for this treatment. Seeing him with a large tumor, especially for a dog of his size, is very concerning for us. Thank you for your cooperation, and we hope that you may help us out for this situation.
