You may need a different ridle, like custom fit
corona cream is great. medicated shampoo helps rubs as well. the specific bridle could also be the issue so maybe try to borrow a different bridle to see if it's your bridle causing the rubbing.
Ordinary sudocrem is good
Penaten works really well. It's a diaper rash cream you can just get from a drugstore
Yeah but during showing I can't have fleece
Have u tried putting fleece on him?
