I can't seem to find a definitive answer to this subject question. We have at least 5 days of solid cold rain fall predicted with no stopping. So far my BO is having the horses out in the rain during the day and in at night. Spirit looked wet and muddy but didn't seem cold by the looks of her.
Other than extra hay, is their something I should be doing differently? She has a blanket but I read that wearing a wet blanket is as bad as wearing no blanket. She's got a little extra weight on her too which helps. The situation that also that concerns me is that there is no supervision of the horses other than at morning and evening feeding times since the BO is on vacation and I live 30 mins away. I check on her during the day but there is not much I can do with her if it's pouring down rain...right? Never owned a horse during a storm so any advice or comments to make me quit worrying are appreciated.
