A vet has transformed a poorly dog's life - by giving him futuristic "robotic" legs so he can walk again. Robbie, an 11-year-old Shetland sheepdog, had been a regular patient at the vets for five years, suffering from multiple problems including paw injuries, skin tumours and orthopaedic issues. After painkillers, surgery, antibiotics and hormone replacement failed to give Robbie a sufficient quality of life, owner Sharman Steel, 63, was at her wit's end. But now Robbie is Britain's first official bionic hound, after having his back legs strengthened with a state-of-the-art exoskeleton.
