"We have already referred to the cause of this condition. It may also be due to injury by the clip of the shoe, by driving a nail too near to the quick, or by any other cause which will excite inflammation. Sometimes it may exist without any external indication until the shoe is removed, unless the hoof is tapped, when it will emit a hollow sound immediately over the separation.

Treatment

This condition, though very objectionable, does not always cause lameness. If a cure is to be attempted, all the separated wall should be removed as far as the white solid horn, every crack or unsoundness being obliterated. A blister should then be applied round the coronet to hasten the secretion of sound horn, and tar and tow bound on the exposed surface until the wall has grown solid and strong.
