More: Callum was diagnosed with osteosarcoma in May 2022, had amputation 6/6/22 and was ready to run the next day. Has been his energetic, happy, ball loving self but he developed an on and off cough about 2 weeks ago and had another symptom that had me take him in for an X-ray, he has soo many lung mets. His vet said probably only a few weeks left for him. He is still so happy and wants to play ball.
