I practice worming with applesauce, my horses are well behaved, no hay/food in their mouth and I still have them managing to spit out what looks like half a tube of Panacur PowerPac dose.
I have four horses that readily eat Vit E gelcaps, Esomeprazole capsules, and Ranitidine tablets readily in their grain. Has anyone gone looking for tablets/capsule horse wormer?
