Treatment varies on a case-by-case basis, but boils are not usually hard to treat. The veterinarian will likely immerse or wipe the boil with hot water to encourage it to rupture. After it ruptures, antibiotic cream can prevent the spread of infection. If there is more than one boil, the same process will apply to the other boils as well.
Living and Management
Boils are not a life-threatening ailment for horses, but care must be taken to ensure that the lesion heals properly and the skin around it is not affected.
A lesion of the skin less than half a centimeter in diameter
A change in the way that tissue is constructed; a sore
Any type of pain or tenderness or lack of soundness in the feet or legs of animals
A localized infection, usually a lesion filled with pus. Can be large or small in size.
