The lakeland vet, overworked, dispirited and sometimes as bleak as his gray sodden fells is Dai Evans, making his rounds from byre to mire since his native Bruton-under-the-Water threatens to become just that. This is another one of Joyce Stranger's animal-loving documentaries and you'll see Dai (and his wife and four children) while he attends a dog -- brutally mistreated with a septic burn; helps a mare to foal during a man-and-beast flu epidemic -- he's ill too; has one child almost die of diphtheria, while another, more happily, is instrumental in inaugurating a Dog Obedience Club; and witnesses a death as well as the conservation of the valley. . . . Do not underestimate the gently whickering appeal of this series -- by now it's more than just an affectionate lick and a promise.
