My horse has a raised, somewhat scaly whitish-pink skin patch, smaller than the size of a quarter, on his nose. The vet said it was a sort of dermatitis. I believe it is left over from the constant chronic sun irritation he gets on the white part of his nose. The whole nose area used to be rough and wrinkly and irritated-looking in the sun.
In the summer I apply sunscreen which he rubs off, but I would like to heal this patch before the strong summer sun begins again. Has anyone had success healing this type of skin irritation?
