Keeley Donovan is in Glasgow discovering how pioneering surgery on guinea pig dog Eva is poised to save shattered lives all around the world. After Eva badly fractured her leg on a walk, hopes began to fade for her recovery. After surgery, infection set in and antibiotics didn’t work. Amputation – or worse – was on the horizon. But her vet had heard about ground breaking research into creating artificial bone and, with Eva’s owner Fiona’s blessing, volunteered Eva as a guinea pig. The fake bone set beautifully and Eva is happily back on all four paws. Keeley meets the professor at the helm of this pioneering work and discovers how nail varnish is part of the miracle recipe. Thanks to Eva and the success of her operation, victims of landmines in war-torn parts of the world could soon have life-changing surgery.
