I have a mid-weight turnout blanket, (I love it, it's a Viking II from sstack.com) and I used it all of last year to keep Bella from growing a winter coat. I want to be able to ride all winter without having to worry about her coat taking too long to dry when she sweats. Right now, in Fall, the night-time temp gets down to about 45 degrees; mid-winter it gets down to 35. I want to start blanketing early enough to keep Bella from starting to grow a winter coat, but not so early (with the mid-weight blanket) that she will be too warm. I also have an unlined turnout sheet. I have searched around online for information on blanketing, but mostly I find sales ads.
So, can anyone suggest a good way get started blanketing for the cold weather? I was thinking a liner under the sheet until it gets colder, or maybe buy her a lightweight blanket then switch to the midweight when it gets colder, or maybe the sheet itself is enough for now. Last year she was at my neighbor's barn and I just did what they did. I'd like to really understand the process so that Bella will be comfortable. I have only one horse, so I can buy her another lighter blanket if I need to (the husband may not agree, but what he doesn't know... ha ha ha).
