Coal, an eight-and-a-half year old hound had his left paw amputated because of cancer last year. He faced being put down because his other legs would be too weak to carry him.
But his determined owner Reg Walker, shelled out thousands of pounds to fit him with a sophisticated bionic leg, which was designed to be compatible with Coal's own tissue.
The titanium alloy used mimics animal hide, allowing the skin and the bone from above to seal the metal implant below without it being rejected by the body.
Vet Noel Fitzpatrick told the Enfield Independent: 'This is unique in that its the world's only implant into which skin and bone grow. It is the holy grail of research.'
