This CHART was intended to be used as a guideline for horse owners residing in the southeastern United States. These recommendations may not apply to other regions due to differences in grass type, soil, daily temperature fluctuation, etc. Please consult your veterinarian with regard to the application of this chart to your area.

Your horse's LEVEL OF RISK for pasture-related laminitis (grass founder) should be determined by your veterinarian. Parameters such as your horse's age, breed, size, history, clinical status and preexisting metabolic disease in combination with local environmental stresses are typically used to determine an individual animal's level of risk.

Many horses are considered to be at VERY HIGH RISK and are consequently prohibited from pasture turnout during certain times of the year. Please consult your veterinarian for specific recommendations.


Please note that the neck of a horse consuming grass excessively high in sugars may become enlarged or excessively firm. If you observe this change, call your veterinarian promptly.
