My Hero Theo

'I'd been in so many scrapes with Theo and he'd always saved me. Those days were the hardest of my life so far and ... at the darkest point, those big brown eyes and that torn ear where I needed them to be. Right there next to me.'PC Gareth Greaves first met Theo, a German Shepherd, when he was a nervous 14-month-old puppy. They were instantly inseparable and police dog Theo became the best partner Gareth's ever had.
