Do people really rush their horses in from a rainfall? My two, and previous two, lived out 24/7 with a field shelter. They have a medium wieght turn out when it is below 5 degrees c at night, and stay out in all weathers, snow, frost, rain, storms. (Elderly pony has 2 rugs on) They are fine and dandy out there. Am i mean or are horses mollicoddled too much?
