She's a hard keeper, 5 y/o TB. She's biiiig though and has the body to carry the weight, just hard to keep the weight once it's there. She has a lightweight stable blanket that currently goes under her medium weight. Her medium weight was a nice new one but her first time out in the new field she ripped the biggest slice down the shoulder so fast forward to now - she gets a new one. I've noticed that she'd still getting quite the winter coat in some areas, and since she's a hard keeper this leads me to believe I should maybe be thinking about a heavy weight rather than another medium weight. We're expecting a cold winter. We already have lots of wind and rain storms, and have had a couple weeks where the wind chill was -15, and day temps are around 3c. But the weather fluctuates quite a bit here so one week it's brutal the next it's decent. I've just never had such a finicky horse. Oh yea and she's on turn out every 3 days, but does have a good sized run out she's free to use at all hours attached to her stall. I plan to clip her at some point, not sure when I've got a good amount of time (she's never been clipped and I imagine it won't be the easiest task).
So medium or heavy weight? Keep in mind that if I get a medium she does have her stable blanky as well, though that is what I do currently and if I were her I'd be cold =S
