Jules Hudson shadows a farm vet in Devon. As the landscape has changed and farms have grown larger the role of the farm vet has changed also. A large part of their role is now on disease prevention rather than simply treatment and they can be crucial in spotting disease outbreaks like foot and mouth which have devastated the countryside in the past. Jules shadows newly qualified vet Jen Hall to find out what's involved and how important the relationship with the farmer can be in protecting animals and the countryside.
