To reduce potential problems when traveling long distances, plan for frequent stops. Horses should be offered water and food every 2 to 4 hours, depending on the weather. In hot humid weather, they should be offered water at least every 2 hours. Horses should not be asked to travel more than 8 hours at a stretch unless absolutely unavoidable. If you have any concerns, have your veterinarian give your horse a thorough physical examination during the week prior to travel.
