Series about the Royal Army Veterinary Corps. This episode looks at how the Corps selects puppies that have the temperament and character to become military working dogs.
Uniquely in the British Army, where women are normally banned from combat roles, the female dog handlers of the RAVC serve on the front line, where their skills are crucial.
On the front line, a young woman and her dog are deep in Helmand province, and a spaniel who has spent his career protecting British troops from IEDs looks forward to retirement.
