My Hero Theo

'I'd been in so many scrapes with Theo and he'd always saved me ...at the darkest point, those big brown eyes were 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 soon became the best partner Gareth had ever had.

During six and a half years of active service, Theo located, tracked and detained suspects, leading to more than 200 arrests. From tackling an arsonist to protecting Gareth from a gang of men during an armed robbery, Theo's bravery knew no bounds. He was also a rock to his partner, providing emotional support as Gareth learned that some of the hardest battles aren't always on the front line.

My Hero Theo is the heartwarming story of one man and his heroic dog - and the bond that sees them go above and beyond the call of duty to keep each other safe.
