Here was Karen's question and once I figure out how to download and post videos from the chat, I will. Bear with me guys, it's a new platform 🤣🤷🏻♀️
The short answer. No.
Blanket your horses when you think they need it. Err on the side of letting them be a little cold instead of warm (unless you have a diagnosed health issue that says otherwise).
Once you take the blankets off a horses coat will rebound and "fluff" up again.
