Okay all I have is a blanket for my horse and she's a little on the skinny sideI'm feeding her grain and lots of hay to fatten her up and keep her warmShe's shivering because it's high 30's and rainingCan I dry her as much as I can with towels then put the blanket on her? Do you think it'd keep her warm or not? I don't need her shivering too muchShe has a run-in barn to be in but that's it.
