Adam Henson takes a look at our favourite four-legged friends in the countryside - horses and dogs. He invites some of the most charming of the breeds onto his farm in the Cotswolds, sees how heavy horses still pull their weight in the fields and finds out whether his gun dog has any natural instincts at all. Looking back into the Countryfile archives to see how the two animals are an integral part of rural life, Adam revisits the time when Julia Bradbury and Matt Baker raced husky dogs in the snowy Cairngorms, when Ellie Harrison became the quarry for a pack of blood hounds and when Jules Hudson spent a day out with the Light Cavalry.
