Please help Apollo!

I work as a vet assistant and today a dog was surrended to us because of the owners inability for afford his life saving care. He is a 2 year old bull terrier. He is such a sweetheart who loves people and dogs alike. He was attacked at a dog park and has sustained 5-10 severe puncture wounds on his chest. He needs emergency surgery tomorrow (5/29) to fix and clean his wounds or he could face serious, life threatening infection. As you may know surgery is expensive! I have temporarily taken the dog in while looking for a new home. Surgery including anesthesia and medication afterwards will be around 720 dollars. I am a college student with a part time job and would appreciate all the help I could get in saving this little guys life!!
