This afternoon I took my daughter Sarah and her four year old three-legged American bulldog, to the vets. She named him Chance because she was looking for a dog and basically had given up but found him by chance. The osteo-sarcoma that brought about his front leg amputation six months ago has spread and it's hard to see your 25 year-old little girl so broken-hearted. He has a large mass on one of his lungs, and lots of joint pain. She took him home for a few days.
