My friend has a horse that is a hard keeper, I do the blanketing and also feeding when he has weekend drill and graining. In wet weather the horse wears a lined rain sheet, and a thin cotton sheet as it doesn't wick moisture away after days of constant rain... We have snow now, and the more on the way. he has access to a deep run in shed. And has a good winter coat, but not real reall thick. On days there is no rain, or snow, I know my friend would like him with out the blanket. My thoughts are that it get super windy around there, and he will get extra hay. And grain several days aweek. I think he should have a lighter rain sheet on, or a quilted blanket for the below zero days. What are your thoughts. Carol I had just taken off his blanket and cotton sheet after icy rains for 2 days, so his coat is a little flat.
