Animal Heroes S01E02 - Episode 2

The second instalment of this documentary series returns to the front line in Afghanistan as the dog squadron go out on patrol detecting explosives and saving lives.

Back in Britain the programme visits the horses of the King's Troop Royal Horse Artillery and sees a new recruit getting ready to pass out and pull his first gun.

A veterinary officer explains what happens to the dogs when they end their service, and he looks after a dog that has accidentally swallowed some explosives. Plus, Animal Heroes speaks to the mother of one dog handler who was killed in action.
