More serious cracks will extend upward and reach the coronary band
Bluetongue is characterised by changes to the mucous linings of the mouth and nose and the coronary band
of the foot.
CODD is identified by the lesions starting on the coronary band
above the hoof, which progresses downward and causes the horn to separate leaving a raw stump.
The news, released in a statement from the stable yesterday, said: 'The problem all stems from a minor injury to the coronary band
[the nail-bed from which the hoof grows] sustained by banging the door of his box the day before winning the Futurity Stakes at The Curragh.
Growing downward from the coronary band
at a rate of three-eighths of an inch every month, three-quarters of an inch every two months (a normal interval between trims), the hoofwall is able to keep up with the normal wear and tear that your horse subjects it to.
