Check Thyroid levels and if medication doses are correct.
Equine Hypothyroidism, low levels of thyroid hormone, can be seen in both foals and adults. Clinical signs include weakness, lethargy, poor haircoat, poor growth, and laminitis. A blood test can determine if your horse has low levels of thyroid hormone. An oral daily supplement, Thyro-L, is available to help horse’s with hypothyroidism maintain normal thyroid levels. If your horse has been placed on this supplement, blood levels should be tested once yearly. Several blood tests may be needed over a period of 6-12 weeks in order to ensure adequate levels have been reached.
