My Haflinger will NOT stop rolling in the mud. And by the time I get out there to groom, it’s dried and caked on. I’ve tried rough brushes (carefully) and can’t get it off. I’m thinking the only way to get it off is by bathing. It’s in the high 50s and really sunny today, do you think a bath would be ok? There is not a cloud in the sky, and it feels a lot warmer than it says it is. Also, how do y’all handle caked on mud in the cold winter months?
