PC Gareth Greaves first met Theo, a German Shepherd, when he was a 14-week-old puppy. Since then they have been inseparable. The best partner Gareth's ever had, Theo has saved his handler's life many times as well as the lives of countless others. In six-and-a-half years of active service, police dog Theo has located, tracked and detained suspects leading to more than 200 arrests. In that time, he has endured broken ribs, been bitten by assailants and been set on fire. From tackling and detaining an arsonist trying to set a house with three children inside on fire, to protecting Gareth from a gang of men with machetes in an armed robbery, Theo's bravery knows no bounds. Time and time again, he has put his own life at risk to save others. This is the heartwarming story of one man and his heroic dog — a bond that sees them go above and beyond the call of duty to keep each other safe.
