  • If the conditions are extreme and you have questions about management.

Excessively hot ambient temperatures can be a source of stress for horses. In my experience, many domestic horses are less tolerant of extreme heat than extreme cold. However, horses adapt surprisingly well if you provide them with basic relief from the heat.


Maintain airflow in enclosed areas with fans. Provide shade and ventilation. Keep trailer windows open for ventilation. If horses are worked in severe heat, provide more rest than usual and reduce your expectations. Ensure that your horse is adequately conditioned for the work expected. Provide electrolytes and frequent access to fresh water.

Assess the horse’s general health using the Whole Horse Exam (WHE), and share any abnormal findings or concerns with your vet.


Your vet may offer other management advice, however if your horse has any other health issue, they may want to examine your horse.
