Unless your horse has a problem there's no need to give probiotics. Equine Generator is fine for any horse.
Sand Clear is OK but IME loose powder works much better than pellets and you need to give enough - 2 cups volume measure, moistened. https://uckele.com/psyllium-husk-fiber-5lbs.html
EMS can cause all those signs except for the coat. Early PPID cases may test with normal ACTH except during the seasonal rise. We are coming out of the rise now but elevations may persist into January. There's not much difference between now and November 5. If results are questionable, ask for a TRH stimulation test.
