Charlie, our English yellow lab, was diagnosed with osteosarcoma in February 2014. He became a tripawd on February 24th, with clear lymph nodes and lungs, but that didn't last long. After three doses of Carbo, in May 2014, x-rays showed lung mets. We briefly tried Palladia, which went well. Unfortunately, Charlie developed unexplained complications in his hind limbs. We said a reluctant farewell on June 11, 2014. Still miss our boy each and every day.
