How to handle equine wobblers syndrome
Consider whether your horse is predisposed.
Some horses are at greater risk of developing wobblers syndrome. Male horses and large, fast-growing breeds like thoroughbreds, warmbloods, and quarter horses seem to develop the disorder most often.
There isn't much you can do to prevent wobblers, but understanding predisposition can help you identify it early on. There is not much evidence to suggest that wobblers is hereditary.
