Well until I got my current horse, last year, I never blanketed; but because she had a rough time getting overheated in the winter while I worked her, I body clipped, and blanketed her. That was last year, and I am hoping because she is used to being worked 'hard' on a regular basis, she won't get so overheated this winter. She's the only horse I have EVER blanketed in the winter (I was in AZ last year, but grew up in the frigid north, of MN).
I am in the Denver area, and from what I hear winter isn't 'hardcore' like where I came from in MN. I hope not, cause I really want to keep my girl in shape but don't want to have to blanket her all year either, hahaha!
I guess that doesn't really answer your question, other than where I grew up, and we NEVER blanketed.
