I need thoughts here :) and maybe experiences.
I have a horse coming in for a two-week trial that the owner has not been blanketing and won't be bringing a blanket or sheet. The horse's coat is thick and more than heavy enough to handle the temps when inside the barn, however, the barn I am at tends to get windy in the paddock and turnout areas and I am worried about a wet chill, rain or snow. While I realize the horse probably wouldn't be able to handle a heavy blanket, is a lightweight turnout blanket or even turnout sheet a good idea for turnout on cold and windy days and for that "just in case" rain or snow shower?
In the event of a wet chill, understanding that the horse would have to be monitored for sweating and so on, would a turnout sheet or lightweight blanket be too heavy in the barn, which is normally about 10 degrees warmer than the outside?
