German Shepherd Argon, who was found abandoned in a Malibu ravine with his mouth zip-tied shut, is making a remarkable recovery after three months of care. The seven-year-old dog, who was severely underweight and diagnosed with lymphoma, has gained weight and trust in his caretakers. He has been undergoing weekly chemotherapy sessions and is expected to complete his treatments in the next eight weeks. The German Shepherd Rescue of Orange County is hoping to find Argon a loving home once he has fully recovered.
