I had huge problems with ongoing fungal bacterial skin problems with my horse. My vet suggested betadine baths, very weak bleach baths, gave him this new injectible treatment, biopsied it. I bathed him so much he smelled like betadine when he sweated. Constant cleaning of tack and brushes. On and on and on.... Someone on this forum suggested giving him injectible cattle vitamin A but giving it orally. Well, I did not have any of that so I have given him high doses of supplements, flax, Omega oils, LMF, super 14 skin supplement, and horseshoers secret,anything with A in it. I really need to get the cattle stuff, would be WAY cheaper. Long story short all skin problems, including his terrible dandruff and all those fungus spots (he looked like an appaloosa for awhile from bald spots) are gone.
