Help Snoozie

Hi my name is Kelly. I have a dog and her name is Snoozie and she's 8 years old. Snoozie had developed a growth on her shoulder. Her vet did a biopsy and then the growth opened up and became infected. Snoozie is on antibiotics and a friend helps me change her dressings.   But, she needs surgery to remove the growth and infected tissue. Without surgery the infection will spread and she will get quite ill and in pain. At that point I'd have to put her down, because I can't let my long time friend suffer. With surgery we will have quite a few years together.  It's going to cost $2000.00 in surgery and post surgery care. I'm disabled with chronic lung disease and severe arthritis and live on low income. That's why I'm asking for help covering her surgery costs. I'd be thankful for any help people can provide.
