My dog needs surgery

My family dog Shasta has developed a tumor on her back left leg the size of an orange. The vet said they could remove the tumor, but it would cost $2000.00usd. In the middle of this pandemic, I'm barley scraping by, & I sadly cannot afford to help her. Both my parents passed away & I was unable to do anything, even with money, but my dog is still able to be saved & I would never forgive myself if I didnt try everything in my power to raise that money & give her a few more years to enjoy life.
