Survival of the Few by Edward Phillips

This is the tail of a small band of Welsh mountain sheep caught up in the foot and mouth crisis on the Welsh hills during 2001 in the UK. Facing imminent slaughter, they take action to escape their inevitable capture. Aided by their good friend Shadow the sheepdog, they escape the hills and seek refuge in the forest below. Two of the group break away and travel south facing cold, hunger and an uncertain future on a quest for help, but what they experience will change their view of the world forever.
