My elderly mare has three Rhino blankets: a sheet, a 100g, and a 250g. But, she runs warm and in spite of her age is blanketed lighter than the other horses where she lives. If her blanket makes her too warm, she won’t eat her hay, and since she’s decided to become a hard keeper this winter, it’s better for her to be a little chilly than too warm if we want to keep her eating.
Assuming not super windy or precipitating:
Above 30, she’s naked during the day. At night she gets a sheet or the 100g if the low is below 40.
20-30, 100g
10-20, 250g
Below that, layer 100g and 250g
The horses live outside with sheds, but BO has stalls for them if it’s really cold… In 2 1/2 years at this barn, they have been in for exactly one night, when it was 12 below with windchill of 28 below.
Neck covers added or removed as needed. But only one neck cover at a time.
She usually doesn’t get her evening blanket on until after it’s dark.
Today, we have a high of 10 degrees and a bit windy so she’s in her 100g and 250g, only the 250g neck cover though. She has as much hay as she can eat in her nets, and the BO is giving her some loose hay as well. I also use leg boots in front when it’s this cold. They go all the way to the ground. We worry about winter laminitis with her.
