Gibson (the Guinness Record holder for the world's tallest dog) was diagnosed with bone cancer back in April and, sadly, he recently lost his battle with the disease. The beautiful Harlequin was undergoing chemotherapy and, when he needed to have his front right paw amputated, his owner started Three Paws For the Cause to raise awareness about canine cancer.
Gibson's vet, Dr. Peter Walsh said:
Last week Gibson began having trouble using his back legs. X-rays showed that the cancer had spread to his spine and his lungs. Ms. Hall made the very difficult decision based on her concern and love for Gibson to have him humanely euthanized. Gibson died peacefully in the loving arms of Ms. Hall.
