Medical help for abandoned dog

 Small dogs owner group found almost frozen and starved pitbull mix named Pita in dog park. We found her temporary home and took her to the vet. She was diagnosed with inflammation of the bladder and her entire body was covered in scars what makes us believe that she was used in dog fights, probably as a bait. After the cure of antibiotics she needs to go on a spay surgery. We need your help for veterinary fees like vaccine, tests before surgery, surgery, treatment of the wounds, food, treatment of parasites... After all she's been going through she's beautiful dog and deserves a beautiful life and home, help us to help her...Any help will be greatly appreciated
