  • If the results of the Whole Horse Exam (WHE) suggest the horse is otherwise normal.

This commonly occurs in horses fed whole grains, especially those that have poor dental health. It is especially common in older horses.


Assess your horse’s general health using the Whole Horse Exam (WHE). Consider your horse’s body weight and the diet you are feeding. Share your findings and concerns with your vet.

Keep in mind that today there are many high quality commercial pelleted feeds available that might be more easily digested and provide better nutrition than what you are feeding.

If you prefer feeding straight grains, consider buying rolled or crimped grains, because these are more digestible. But keep in mind that these may provide more nutritional value (particularly available carbohydrate), so make feeding changes slowly and be cautious of grain overload, colic and laminitis.


Your vet may suggest that you feed your horse more easily digested pelleted feeds, and/or may also suggest that they perform a dental exam to determine whether dental work is needed.
