So I couldn't figure out why Foxy wasn't getting better anymore after I took him off of Safe Choice Original that he was highly allergic to. Hives, atrophy, flared hooves, muscle pain were all symptoms from it. He accidentally got it once two weeks after I took off of it, just two bites, and still broke out. I put him on Triple Crown Senior that has no corn when I saw a couple of years ago he had hives before when I gave him Purina Ultium, just didn't know that was the problem at the time, just had taken him off of it because it was not improving his topline. Today, I notice he had a slight break out on his neck and just was looking at his atrophy on his withers, neck and shoulders trying to figure out why they weren't improving anymore and his muscle pain. Was thinking I was over doing the massages and laser or even saddle fit. Well, it turns out at least one feed mill puts corn in their oats even though the tags say they only have oats in the ingredients. And its the one my barn uses, it says Ag Feed, but that appears maybe that is a co-op?
