The people who show their horses, blanket the horses. It prevents them from properly adapting to cold weather by impeding their hair growth. I never blanketed any of my horses and they all grew good coats and did fine. No one blankets the wild horses and they do fine even in the sub -30°F weather.
That’s all fine and dandy when the horses are accustomed to that weather, but horses that were born and raised in Texas where the sun still doesn’t set until 7-7:30 during December means they don’t grow in their coats to handle 40° drops such as yesterday to today. Hair growth is directed by photosensitivity, not temperatures.
Yep...it is freezing down there already.
It’s freezing rain here! It’s October, not January 
Grab the winter gear. I’m not looking forward to driving home, everyone loses their minds on the roads when it’s cold and rainy.
Horses are tougher than you think. While the hair growth is related to photosensitivity, it is also related to temperature. Around here the hair gets much thicker and longer in really cold weather irregardless of how much sunshine there is.
I do realize this, but the two that I named as the shivers are also our hard keepers, one being 19 and the other a 5 year old miniature who colics when he gets too cold, so I would rather them be supplemented warmth rather than use their energy needs to keep them warm. Our other three, specifically the Belgian from Pennsylvania who loves these temps, are not the ones I was worrying about as they are all easy keepers, and grow a sufficient amount of coat to keep them warm.
It is! I loved it!
