Isabel's Surgery

Earlier this week, I discovered a small mass under Isabel's tail. The vet determined that it is a cyst, and after taking samples of it, discovered that there are some cancer cells inside the cyst, and it needs to be removed. The surgery will cost anywhere between $900 and $1100, and I simply can't afford that, as I barely live paycheck to paycheck. So I am forced to humble myself and ask for help again. I love this little dog more than anything, and I would go to any lengths to help her, so please, if you can, any assistance would be appreciated.
