My horse has recently developed the waxy build up of “crud/gunk” on the fronts of his hind cannon bones. Hopefully that is descriptive enough. Usually when I see this forming on any of my horses a good very gentle curry to lift off the stuff and then I shampoo the legs with some sort of shampoo that helps prevent fungus/bacterial infections making sure their legs get good and dry afterward. This usually clears things up within a week.
For this particular horse he is currently recovering from a ligament injury/surgery and his leg is wrapped 24/7. Unless he is being bathed or drying from the bath the leg is wrapped. Does anyone have any sprays or leave on treatments that they have used that are safe to use under a wrap? I really wish his leg could have light and fresh air but that is just not in the cards at the moment.
