Surgery for Brody

Hey guys, Brody is my Great Dane and he hit his tail on something about a month ago, hard enough to break the skin.  This condition is known as happy tail and let me tell you, it is anything but happy.  His tail got infected and unfortunately the bacteria is not responding to the antibiotics and his tail is dying off.  We need your help to get the surgery to remove the unhealthy section and save his life.  This has reached a critical stage and needs to happen within the next week or so to keep him from becoming septic.  It would mean the world to me if you could help me get Brody the surgery he needs and get him back to a happy healthy dog.
