We cannot assume he as dog does not exhibit hope that his life would somehow improve. Angels life and chances of survival did improve. After weeks of acute care he regained some energy. However the steroid treatments were taking a toll. He had been only 51 pounds when he entered the clinic, now he was ballooning in weight from the prednisone.
Steroids interfere with wound healing, so it is always a double edged sword.
He still needed to over come all the complications. These treatments can have the potential to subject the patient to permanent organ damage and other complications including diabetes. Our modern medicine and Angel's vet gave him the best care and treatment that was available so he would have a chance to overcome the massive septic infection than ran ravage in his systemic system. Time would tell. All the while Angel was fighting for life.
