I hate blanketing but…you gotta horse losing weight and until you figure out why and solve it and get headed back in the right direction…(sure enough this week we found two more diseased molars that were extracted - they were so loose they wiggled - poor girl) AND then the universe blesses you with a PSSM horse who is noticeably grumpy if chilly. But I digress…
And not only is there the great challenge of having them warm, not cold, and not hot. Because if they’re not warm what is the point of it all and if they are hot you’ve got a horse that could easily colic it would seem.
So yes, the sun, the wind the difference in temp at night versus during the day. And then there’s learning each horse and do they run hot or cold, right? My mare has barely a coat and runs hot. She is mostly good in a 100gram - unless we get to zero.
My PSSM guy who spent the first 6 years in the Big Horn Basin in WY with brutal weather…runs cold. Maybe it’s his PSSM doing that? And he has a thick, beautiful heavy coat. He lives mostly in a 200 gram and we go 300-400 if there’s wind and in the teens.
But not if it’s sunny, no wind and temps go to 30. Having them home and being able to check them on the weekends has me very aware they can get hot too quick.
There’s a large consensus here about the value of 100 grams and that is a really handy blanket for sunny, windy but still chilly-to-cold and you don’t get the horse in trouble temp-wise. Over heated.
I also hate blanketing because I have a strong opinion that the pressure on the vertebrae at the withers makes them sore. So I’m switching out a lot and do like a Wug thinking it’s a better design to avoid that.
