However, she is an outdoor horse in Alberta. Temperatures in Edmonton are hovering around the 0*C mark, but drop down to -10*C or so on some days. It's not cold enough for a heavy winter blanket, but definitely not warm enough to send her out naked... is it possible to buy just one blanket to use on her from now until spring shows up and brings nicer weather?
Someone recommeded a stable sheet, but that seems a little too light. I was looking at waterproof turnout blankets or lightweight winter blankets. What would you recommend? What fill should I look for?
