Hoof Cracks
February 26, 2009
Quarter cracks. Sand cracks. Clefts. There are lots of names for cracks in your horse’s feet. The question is, when should you call for help if you see a crack?
Sand Crack
If the crack originates at the ground and moves up the hoof toward the hairline, we often call it a sand crack.
These are the most common type of cracks and usually begin with a foreign body getting caught in the hoof wall and starting a crack. Once it is there, it takes some care and some time to grow out. But unless your horse is visibly sore from it, it isn't an immediate danger.
Quarter Crack
If the crack originates at the hairline and moves toward the ground, we call it a quarter crack. These are a bit more troublesome.
They are caused by an imbalance in the hoof that is attempting to right itself. The treatment of these almost always involves some sort of barshoe to stabilize the crack and can involve various patches to immobilize the affected area. This type of crack is reason alone to call your farrier.
With either of the preceding, if bleeding is present, call your farrier immediately!
Cleft
We also commonly see a horizontal crack (parallel to the hairline) that grows down the hoof. This is called a cleft.
Clefts are caused by abscesses rupturing at the coronary band and by sudden compromises in the hoof's circulation. While bad, it’s not an immediate risk to your horse’s soundness. The exception is when a severe abscess ruptures in such a way that the horse is in danger of losing a major portion of its hoof. These are usually very apparent.
This time of year we also see vertical cracks that are very superficial on the hooves. These are attributed to wet conditions and extreme temperature changes. A little rasp work usually clears them right up.
