His military career, which has included tours of Iraq and Afghanistan, lasted over twenty years. Since publication of the Sunday Times bestseller One Dog at a Time, Pen has left the Marines to run his charity Nowzad Dogs and - when time allows - an outdoor adventure company. Pen is married to Lisa and they share their home with five dogs.Pen Farthing has won The Dogs Trust Dog's Best Friend Award and the IFAW Pets and People Award. His dogs Nowzad and Tali were nominated for the Crufts Friends for Life Award. More details about Nowzad Dogs can be found at www.nowzaddogs.com.
