Did you catch The Secret Life of Dogs last week? We BAWLED. Tonight Martin Clunes is back in action and this time he's taking a look at the roles that working horses play in our modern lives. He'll be travelling across Europe and America to find out just how important our four legged friends are before returning home to his farm in Dorset, and his own Clydesdales (the Budweiser horses to you and I) Ronnie and Bruce. These "lovable but uncontrollable teenagers" are off to hoof camp to learn a thing or two about working life.
