Horse has mud fever (got it in the summer when we hadnt had any rain for months) ,anyway, hadthree visits from vet different vet each time, cos horse wont let me near his leg because he is so sore so had to be sedated. i have had three lots of advice now, not all the same ! Horse has quite a large patch of scabby skin which I thought I was on top of, but now scabs have virtually exploded all up the leg and ned has v swollen and sore leg with loads of scabs. First vet clipped original area, but third vet hasnt recommended clipping area now affected. One vet said keep covered, other vet leave uncovered. What are your experiences, and best advice to get rid?
