I've been taking care of a horse for someone and she's the definition of why people think mares are terrible. She's so sweet and will cuddle with you but the second the tack comes out she no longer wants to cuddle. She also hates other horses. Her saddle fit has been checked out by a professional, she gets regular chiropractic adjustments and massages, etc. she's just marish. People have suggested I put her on Mare Magic. I think it's by smartpacks but I'm not sure. Has anyone seen a big difference in their mares on this supplement? Would you suggest it for her?
