I use a blanket soley for the fact that I show around november, december, janurary, feburary. Im an odd one, but I would rather spend all day in the cold at a hunter show, than in the hot Texas heat. Anyway, most show judges don't apprecitate the cuteness factor of a fluffy pony, so I blanket my horse to keep her coat nice and sleek. I also work her hard in the winter (I jump) so a really sweaty pony (my horse sweats ALOT, more than average) is bad news. So I get to go buy a cooler, working cooler, turn out sheet, and stable sheet this weekend. Luckily we already have a mediuum weight blanket. If you are worried about your horse getting chilled in workouts, invest in a working cooler, they are inexpensive, and very handy. Also invest in a full sized cooler (fleece) it prevents your horse from getting chilled, while alowing him/her to dry. Hope I helped!!
