Help Gucci with her medical bills

Doing this is our last resort. We found out our loving pitbull Gucci has cancer (osteosarcoma) in the mouth on July 14th. We had surgery done to remove the tumors that costed us $1100. But they have came back in less than a month. We can not afford more surgery and it's progressing so quick that surgery is not going to help now. We have a lot of vet bills due to emergency visits like when the tumors start bleeding or the cancer spreaded to her eye recently. We decided to put her on pain medication to help ease the pain and help her get through the day. We have not decided to put her to sleep due to the fact she has lots of energy yet and acts like a puppy. She adores spending time with kids and laying on the couch with her cats. Car rides are her favorite past time. We're not ready to let any of that go yet. All of this is being charged to a credit card that we are having a hard time paying off. This is why I am asking for help. We would appreciate anything that anyone can do. Thank you in advance!
